eba22b7551 nic_router: rework updating of TCP/UDP links
* Update links from forward rules only with forward rules and links from
  transport-routing rules only with transport-routing rules. Besides raising
  the performance of the code, this also fixes a former bug that allowed
  forward-rule links to falsely stay active because of a transport-routing
  rule that matched the client destination ip and port.

* Don't use good-case exceptions for updating TCP/UDP links on re-configuration
  of the router.

* Make conditions when to dismiss a forward rule easier to read.
  * Introduces != operator to the public Port class in the net library.

* Fix unnecessary log message that a link was dismissed when only a potentially
  matching forward rule turned out to be not matching.

* Apply Genode coding style to if statements with a single body statement.

845694bc44 nic_router: fix updating UDP/TCP links
This fixes a bug that was introduced by this earlier commit:

"nic_router: find forward rules w/o exceptions"

The NIC router used to falsely dissolve TCP/UDP connection states when
reconfiguring although the connection states were still legal according to the
new config. The reason was that the above mention commit nested lambdas but
missed to return from the last nesting level when having found a configuration
that legitimates the connection state.

1b1a9ca95c nic_router: fix bad connection states on IP change
When a domain receives a new dynamic router IP address and that domain has
active connection states (TCP/UDP/ICMP) from another domain with NAT applied,
the connection states used to stay active while becoming obsolete. They
become obsolete because their identification and their packet processor
use the old routers IP address due to NAT.

One consequence was that connections became dysfunctional when the server
domain received a new dynamic router IP address. Request packets were still
routed from client to server, but when entering the server, their source IP
address was the outdated router address. Consequently, the server responses
used the outdated address as destination and the router dropped the responses
because it did not know this address anymore.

This commit fixes the problem by letting a domain destroy all its connection
states that were initiated from within other domains whenever it detaches from
its current IP configuration.

Strictly speaking, it is not necessary to destroy all connection states, only
those that the domain applies NAT to. However, the Genode AVL tree is not built
for removing a selection of nodes and trying to do it anyways is complicated.
So, for now, we simply destroy all connection states.

Note that the other way around was handled correctly already. When a domain
detaches from its IP config, all interfaces of that domain destroy all the
connection states they created (towards other domains).

7a7cac57d9 nic_router: futile ip config updates on dhcp renew
If the IP config does not change on updates to the router IP config of a domain
change (a common case on DHCP RENEW), prevent detaching from the old config and
attaching to the new one. Because this would not only create unnecessary CPU
overhead but also force all clients at all interfaces that are listening to
this config (via config attribute 'dns_config_from') to restart their
networking (re-do DHCP).

ff2176a586 vfs,libc: support write fds in select
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.

Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.

5ad98f2b7c vfs,libc: introduce Vfs::Env::User interface
The new interface is meant to replace the 'Vfs::Io_response_handler'.
In contrast to the 'Io_response_handler', which had to be called
on a 'Vfs_handle', the new interface does not require any specific
'Vfs_handle'. It is merely meant to prompt the VFS user (like the libc)
to re-attempt stalled I/O operations but it does not provide any
immediate hint, about which of the handles have become ready for
reading/writing.

7d8d4f4532 vfs,libc: deferred wakeup of remote peers
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.

The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.

The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.

4bacba431b nvme_drv: do not mask interrupts
During interrupt handling the driver masked and cleared interrupts as
recommended in the spec to prevent spurious or unnecessary interrupts
from occurring.

Due to the way the current implementation operates new Block requests
got submitted while handling completions for already finished ones.
Since interrupts where masked at this point the controller did not
generate interrupts when the newly submitted requests got completed.

As the mask/clear optimization is apparently not strictly needed and
according to the spec undefined when using MSI-X it is removed.

49b4b8597d os/pin_driver: support for time-multiplexed in/out
This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.

To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

c83f307b62 nic_router: consider DHCP client optimization
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.

99254b4d52 nic_router: bind link state to remote DNS config
The NIC router README claims that the 'dns_config_from' attribute in a DHCP
server configuration binds the propagated link state of all interfaces at the
domain of the server to the validity of the IP config of the domain that is
given through 'dns_config_from'.

However, this was not true. The router missed to implement this detail which
led to clients of such a DHCP server sending DHCP DISCOVER packets too early.
These early DHCP DISCOVER packets were dropped by the router potentially
causing a big delay until the client started a new attempt. Unnecessary long
network boot-up delays were observed with at least the lwip run script and
Sculpt on the PinePhone and could be tracked down to this former
inconsistency in the router.

This commit fixes the inconsistency.

907641f6ea lx_fs: improve safety when using dir handles
This patch consolidates the repetitive error handling across the RPC
functions, which take node handles or directory handles as arguments.

During this change, I noticed that directory handles - which are values
provided by the client - were not checked for their type before being
used. A misbehaving client may open a file, manually construct a
directory handle using the number of the file handle, and invoke a
directory operation at lx_fs, which would then wrongly access a file
node as directory node.

This patch solves this issue by introducing two distinct methods
_with_open_node and _with_open_dir_node, which perform the respective
safety checks.

79cc9af212 nic_router: intf. con/destruct reports link state
Creating and destructing an interface was not considered a change of its real
link state as defined in the description of the <report link_state_triggers="">
config attribute in the router's README. In case of Uplink sessions this is
obviously a problem as they communicate their real link state through session
lifetime. But also in case of NIC sessions it's a possible to create an
interface that is immediately "up" after creation or destruct an interface
without its link state going "down" beforehand.

Taking into account also the practical application of the
<report link_state_triggers=""> attribute, reporting only on destruction and
construction of interfaces that are "up" seems shorthanded. This is because a
report-receiver most likely needs to be able to synchronize the lifetime of
the objects that keep track of the link states with the lifetime of the
corresponding sessions.

That said, with this commit, the router triggers a report update on each
session construction/destruction when <report link_state_triggers=""> is
set.

aff1db1543 nic_router: generate reports asynchronously
The NIC router used to generate reports triggered by IP config changes or link
state changes synchonously, i.e., inline with the activation context that
caused the change. This has two disadvantages. First, it can lead to an
excessive number of report updates in situations with quick bursts of
triggering changes. In such situations it is preferable to collect the changes
and reflect them with only one final report update.

Second, synchronous reporting may happen while the router is in a state that
leads to an incorrect report (e.g. during reconfiguration). To prevent this
from happening, the router so far explicitely switched off reporting when
entering incoherent states and back on when leaving them. However, this
solution is error-prone as the exclusion windows must be maintained manually.

Both issues can be solved by not directly generating a report when necessary
but instead submitting a signal and letting the signal handler do the work in
a dedicated activation context.

cc9368ccb4 os: add File_system_session::num_entries RPC
This patch splits the querying of the number of directory entries from
the directory's 'status' information. Subsuming the number of directory
entries as part of the status makes 'stat' calls too costly for some
file systems that need to read a directory for determining the number of
entries. So when stat'ing the entries of one directory that contains sub
directories, all entries of each sub directory are visited.

Thanks to Cedric Degea for pointing out this performance bottleneck!

With this change, the 'status' function returns a 'Status::size' value
of 0 when called for a directory handle.

b82d83e271 nic_router: handle bad DNS in DHCP ACK gracefully
The DHCP client of the NIC router used to end up in an uncaught exception if
an IP address in the DNS server option of a DHCP ACK was invalid. This commit
makes the 'Dns_server' constructor (where the exception originated from)
private and instead introduces a public lambda method 'construct' that calls
one lambda argument on success and another on failure. This is also in line
with the most recent changes to the 'find_by_*' methods of other classes in
the NIC router and contributes to the goal of reducing expensive exception
handling.

054990aafa nic_router: fix net session aliases
The Interface class of the router is an abstraction for NIC client sessions,
NIC server sessions, and Uplink sessions. Nonetheless, Interface generally used
to use the packet stream types of the Nic namespace and it worked because the
Uplink packet stream types are factually the same (the are typedef'd from the
same base type templates with the same parameters).

The initial intention of this issue was to remove dependency on the diverse
packet stream stream types from Interface. However, this turned out to be more
tricky than thought. The Interface class calls function templates on the packet
stream types, making a generic virtual interface impossible. And moving the
calling code to the session classes as well would produce a lot of redundancy.

Therefore, this commit removes only the use of the Nic namespace in the
interface.* files by typedef'ing the packet stream types from the generic
Genode type templates with the same parameters as in Nic and Uplink.

e32157e21b nic_router: packet allocation w/o exceptions
In overload situations, i.e. when a sender fills up the entire buffer, we land
in situations where the sender receives an ack_avail signal, releases one
packet, allocates and sends a packet and fails to allocate a second packet.
This is especially relevant if the receiver does not batch ack_avail signals
(such as vfs_lwip). In those ping-pong scheduling scenarios, the overhead from
catching the Packet_alloc_failed exception becomes significant. In case of the
NIC router, we will land in an overload situation if the sender is faster than
the receiver. The packet buffer will be filled up at some point and the NIC
router starts to drop packets. For every dropped packet, we currently have to
catch the Packet_alloc_failed exception.

This commit adds a new method alloc_packet_attempt to Packet_stream_source that
has almost the same signature as the older alloc_packet method but returns
an Attempt<Packet_descriptor, Alloc_packet_error> object. As the method already
used the allocator back end exception-less, changes on lower levels were not
needed. Furthermore, the NIC router was modified to use the new exception-less
alloc_packet_attempt instead of alloc_packet.

433029c3a6 nic_router: find ARP cache entries w/o exceptions
Replaces the former implementation of the 'find_by_ip' method at the data
structure for ARP cache entries. This method used to return a reference to the
found object and threw an exception if no matching object was found.

The new implementation doesn't return anything and doesn't throw exceptions. It
takes two lambda arguments instead. One for handling the case that a match was
found with a reference to the matching object as argument and another for
handling the case that no object matches.

This way, expensive exception handling can be avoided and object references
stay in a local scope.

e2086ac8e4 nic_router: change max_packets_per_signal default
According to a benchmarking series on Zynq (base-hw) and x260 (base-nova) using
test-nic_perf_router, increasing the 'max_packets_per_signal' has a significant
effect on the packet throughput. By increasing the default value from 32
to 150, we could gain a few hundred Mbit/s. Increasing the value further
does not seem to have such a strong effect, though.

d5b1d9466a nic_router: clear ARP cache when domain is down
Whenever a domain looses all its interfaces or the link state of all attached
interfaces is down at once, the domain potentially moves to another Ethernet
segment and should therefore consider its ARP cache to be outdated.

RFC 826 states that "... If a host moves, any connections initiated by that
host will work, assuming its own address resolution table is cleared when it
moves. ...".

Therefore, this commit introduces clearing the ARP cache and the initially
stated events.

This commit was motivated by an issue with the PinePhone Modem and USB NIC.
On the PinePhone, the Modem has its own OS and acts as direct gateway to the
outer world for the USB NIC that is driven by Genode. However, whenever the
Modem gets restarted, Modem and USB NIC receive a new MAC address. This used
to conflict with the NIC routers ARP entry for the Modem that didn't cease to
be valid.

With this commit, the integrator of such a scenario at least has a convenient
way of fixing this by ensuring that all interfaces at the USB NIC domain go
down when resetting (e.g. by ensuring that the USB NIC is the only interface at
that domain).

within the Platform::Connection utilities, and register temporarily
an Io_signal_handler to wait for changes of the devices ROM, and
try the device aquisition again. Thereby, simple drivers so not have
to take the burden to do so.

To enable this feature for all drivers, we always have to export a
devices ROM, but limit the information about physical resources
(I/O memory addresses, IRQ numbers, I/O port ranges) to clients with
'info=yes' in their policy description.

cacb6136fa app/pci_decode: prepare pci device information
To discharge the generic platform driver from certain PCI bus scanning,
and ACPI + kernel specifics, this commit introduces a new component,
which consumes the acpi drivers report and the platform_info from core
to prepare a devices ROM for the platform driver that contains all
PCI devices and its resources.

USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.

The configuration was extended so that in case the device interface

a45aabe68c usb_block: handle block requests in Signal_handler only
Before this commit, the block-request handler was implemented as
Io_signal_handler and, additionally, the USB driver called the
block-request handler on request completion directly on I/O level. This
is generally a bad idea because I/O handlers should avoid to have direct
global side effects. In contrast, application logic should be
implemented in way that it consumes atomic state changes after I/O
completed. Now USB I/O completion locally submits a signal to the
block-request Signal_handler.

b9141f98af test/black_hole: fix "packet alloc failed"
The Uplink_test used to end in an uncaucht exception about a failed packet
allocation on several x86_32 platforms.

* Destruct and re-construct the corresponding TX packet allocator during a
  link-down-up step in the Uplink test. Fixes the exceptions but results in a
  never ending test.
* Decouple the link-down-up steps from the handling of packet stream signals
  by simply triggering it with a local periodic timeout of 1 sec period.
  This prevents that the Uplink_test never finishes because it destructs the
  Uplink connection too often.
* The test finishes not before at least 3 link-down-up steps were executed.
* Replace the Allocator_avl's used for the TX packet allocators of the Nic
  and Uplink Connection with the better suited Nic::Packet_allocator.

ef8c98cb71 nic_router: merge packet stream signal handlers
The NIC router used to handle each type of packet-stream signal with a distinct
method in the Interface class. However, merging those methods has advantages.

It ensures that sent packets that were already acknowledged by the counter side
are always released before handling received packets. This frees packet stream
memory which facilitates the potential allocation of response packets while
handling received packets. Furthermore, it simplifies the code and reduces the
number of entry points into the router.

This commit also removes the installation of signal handlers at packet streams
for events that are of no interest for the router (TX-ready-to-ack /
RX-ready-to-submit at NIC sessions and RX-ready-to-ack / TX-ready-to-submit at
Uplink sessions).

bb26a986e6 sculpt: add trace_logger as optional launcher
This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:

- Add 'trace_logger' to the 'launcher:' list of the .sculpt file

- Either manually select the 'trace_logger' from the '+' menu,
  or add the following entry to the deploy configuration:

    <start name="trace_logger"/>

By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.

be0a1742ac base: distinct TRACED from ATTACHED trace subjects
This patch makes the trace-subject state as reflected to the trace
monitor more accurate.

Until now, a subject could be in UNTRACED or TRACED state. In reality,
however, there exists an intermediate state after the trace monitor
called 'trace' for the subject but before the subject locally activated
the tracing (done when passing a trace point). This intermediate state
was reflected as UNTRACED. Consequently, threads that never pass a trace
point (e.g., just waiting for I/O) would remain to appear as UNTRACED
even after enabling its tracing by the trace monitor. This is confusing.

This patch replaces the former UNTRACED and TRACED states by three
distinct states:

  UNATTACHED  prior any call of 'trace'
  ATTACHED    after a trace monitor called 'trace'
              but before the tracing is active
  TRACE       tracing is active

a9022d8451 sandbox: improve CPU-quota accounting
The existing assignment of CPU quotas did not anticipate the dynamic
reconfiguration of init. It merely tracked the available CPU quota by
deducing the consumed amount from a global variable but never
replenished the value. This worked for static scenarios but failed in
situations where components are dynamically re-started.

So far this deficiency remained detected because CPU quotas were not
used in highly dynamic systems like Sculpt OS. However, this has
recently changed by commit "sculpt: assign CPU quotas".

The patch improves the accounting by mirroring the existing handling of
RAM and cap quotas. Note that the CPU-quota accounting is still rather
limited. In particular the dynamic rebalancing is not yet supported.

ca9460aead event_filter: touch/press untouch/release sequence
This commit changes the touch-click filter to adhere the following
sequence:

  touch         (physical)
  press         (artifically generated)
  release       (artificially generated)
  release_touch (physical)

This order is important because nitpicker's focus handling takes
press/release events into account. If the release-touch event appears
before the release event, nitpicker subsumes the release-touch event
to the sequence that started with the press event, instead of handling
it as a free-standing event.

c2efa5406e xml_node: support backslash as attribute value
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.

The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.

The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.

This patch makes nitpicker's "clicked" report useful for the detection
of clicks outside of any client. This is needed in situations where the
dialog should close when clicking outside its screen area. In the new
version, a click outside any client results in a report without a
'label' attribute. Furthermore, the report is augmented by the sequence
number of the click, which allows for freshness checks by the consumer of
the report (i.e., sculpt_manager).

e4f62380d7 base: Pd_session::dma_addr, Pd_session::attach_dma
This patch enhances the PD-session interface with the support needed for
user-level device drivers performing DMA. Both RPC functions are
intended for the direct use by the platform driver only. If invoked for
PDs that lack the managing-system role, the operations have no effect.

The 'dma_addr()' RPC function allows the platform driver to request the
DMA address of a given RAM dataspace. It is meant to replace the
'Dataspace::phys_addr' RPC function.

The 'attach_dma' RPC function adds the given dataspace to the device
PD's I/O page table. It replaces the former heuristics of marking DMA
buffers as uncached RAM on x86.

With this patch, the UNCACHED attribute of RAM dataspaces is no longer
used to distinguish DMA buffers from regular RAM dataspaces.

83626b18f0 uplink_client_base: remove unused code
So far, the generic Uplink connection code considered NIC drivers to transmit
connection RX packets in three different manners. Most of the drivers follow
the "normal" way of transmission with only one driver callback from generic
code. The monolithic USB NIC-driver, however, used to send in a "burst" mode
that required a dedicated path with multiple driver callbacks in the generic
code. And then there were drivers that had a fully custom function for doing
transmissions.

Also for handling connection TX acks, there was a "normal" and a
"custom handler" way.

Today, all NIC drivers in the Genode repos and the Genode-World repo follow the

b723b11b30 Modularize Sculpt OS image creation
This patch equips Sculpt with the ability to customize the system image
in very flexible ways.

All customizable aspects of the image have been relocated from the
former sculpt.run script and the accompanied gems/run/sculpt/ directory
to a new location - the sculpt/ directory - which can exist in any
repository. The directory at repos/gems/sculpt/ serves as reference.

The sculpt directory can host any number of <name>-<board>.sculpt files,
each containing a list of ingredients to be incorporated into the
Sculpt system image. The <name> can be specified to the sculpt.run
script. E.g., the following command refers to the 'default-pc.sculpt'
file:

  make run/sculpt KERNEL=nova BOARD=pc SCULPT=default

If no 'SCULPT' argument is supplied, the value 'default' is used.

A .sculpt file refers to a selection of files found at various
subdirectries named after their respective purpose. In particular, There
exists a subdirectory for each file in Sculpt's config fs, like
nitpicker, drivers... The .sculpt file selects the alternative to use
by a simple tag-value notation.

  drivers: pc

The supported tags are as follows.

*Optional* selection of /config files. If not specified, those files are
omitted, which prompts Sculpt to manage those configurations
automatically or via the Leitzentrale GUI:

  fonts
  nic_router
  event_filter
  wifi
  runtime
  gpu_drv

Selection of mandatory /config files. If not specified, the respective
'default' alternative will be used.

  nitpicker
  deploy
  fb_drv
  clipboard
  drivers
  numlock_remap
  leitzentrale
  usb
  system
  ram_fs

Furthermore, the .sculpt file supports the optional selection of
supplemental content such as a set of launchers.

  launches: nano3d system_shell

Another type of content are the set of blessed pubkey/download files
used for installing and verifying software on target.

With the new version, it has become possible to supply a depot with the
the system image. The depot content is assembled according to the 'pkg'
attributes found in launcher files and the selected deploy config.
The resulting depot is incorporated into the system image as 'depot.tar'
archive. It can be supplied to the Sculpt system by mounting it into the
ram fs as done by the 'ram_fs/depot' configuration for the ram fs.

It is possible to add additional boot modules to the system image. There
are two options.

  build: <list of targets>

This tag prompts the sculpt.run script to build the specified targets
directly using the Genode build system and add the created artifacts
into the system image as boot modules.

  import: <list of depot src or pkg archives>

This tag instructs Sculpt to supply the specifid depot-archive content
as boot modules to the system image. This change eliminates the need for
board-specific pkg/sculpt-<board> archives. The board-specific
specializations can now be placed directly into the respective .sculpt
files by using 'import:'.

To make the use of Sculpt as testbed during development more convenient,
the log output of the drivers, leitzentrale, and runtime subsystems
can be redirected to core using the optional 'LOG=core' argument, e.g.,

  make run/sculpt KERNEL=linux BOARD=linux LOG=core

The former pkg/sculpt-installation and pkg/sculpt-installation-pc
archives have been replaced by pkg/sculpt_distribution-pc, which
references the generic pkg/sculpt_distribution archive. Those pkgs are
solely used for publishing / distribution purposes.

This comes up when building the code with clang 13. It happens due to

addresses. Therefore, we align the allocation to 2 bytes, so the IP

3cc6df3116 base: tighten affinity handling
This patch improves the robustness of the CPU-affinity handling.

- The types in base/affinity.h received the accessors
  'Location::within(space)' and 'Affinity::valid', which alleviates
  the fiddling with coordinates when sanity checking the values,
  in init or core.

- The 'Affinity::Location::valid' method got removed because its
  meaning was too vague. For sanity checks of affinity configurations,
  the new 'within' method is approriate. In cases where only the x,y
  values are used for selecting a physical CPU (during thread creation),
  the validity check (width*height > 0) was not meaningful anyway.

- The 'Affinity::Location::from_xml' requires a 'Affinity::Space'
  as argument because a location always relates to the bounds of
  a specific space. This function now implements the selection of
  whole rows or columns, which has previously a feature of the
  sandbox library only.

- Whenever the sandbox library (init) encounters an invalid affinity
  configuration, it prints a warning message as a diagnostic aid.

- A new 'Affinity::unrestricted' function constructs an affinity that
  covers the whole affinity space. The named functions clarifies
  the meaning over the previous use of the default constructor.

- Core's CPU service denies session requests with an invalid
  affinity parameter. Previously, it would fall back to an
  unrestricted affinity.

1a9fad4022 virtio_nic: Tweak default buffer sizes.
After VirtIO::Queue refactoring buffers no longer share the same
dataspace as VirtIO rings. This makes optimal buffer calculations a lot
easier. In this case 64 buffers 2kB each will need precisely 128kB of
RAM. Previous value of 2016 will just waste 768b.

643747b912 os: Refactor VirtIO::Queue implementation.
The key changes in this patch are:
* Buffer allocation is moved into a separate Buffer_pool helper. The
  implementation of the buffer allocation strategy does not change.
  The helper allocates a single RAM dataspace and splits it in multiple,
  equally sized chunks.
* Management of main descriptor ring is enacapsulated in Descriptor_ring
  helper class.
* Use separate RAM dataspaces for descriptor rings and buffers.
  Previously both of them were packed into a single dataspace. This
  might have been more RAM efficient, but IMO it made the code uglier and
  harder to understand.
* All of the VirtIO::Queue members are now initialized on the class member
  initializer list. This is possible due to previously listed changes.
* Since all VirtIO::Queue members are initalized on member initalizer
  list, some additional ones can be marked as const, ex _avail, _used ring
  pointers.
* Move descriptor writing code into a common method used by both
  write_data and write_data_read_reply members. This avoids some code
  duplication between those methods.
* Get rid of request_irq argument that most public VirtIO::Queue methods
  accept. None of the existing drivers use it and I doubt this will
  change any time soon.
* Use Genode namespace by default in Virtio.

This patch also fixes at least one bug that I discovered while working
on VirtIO block device driver. Namely, when chaining descriptors only the
first descriptor in the chain should be exposed in the available ring.

162ddb1fdb virtio: fix len calculation
Thanks to Piotr Tworek for the fix and his explanation as follows:

The basic idea is to try to fit payload data into the descriptor used to
send the header. If there is no payload, or the payload fits exactly
into the remaining space in the header decriptor, len should be 0 and
only one descriptor should be used. In such case the "next" and "flags"
members of the descriptor structure should be set to 0.

In case there is some extra payload data to send, but its size is
bigger than the remaining free space in the descriptor used to send the
header, len should contain the remaining size of the payload that
can't be sent via the header descriptor. The code will then chain
additional descriptors to handle this remainder.

With the len variable shadowing, the code will never queue the remaining
data.

This implements the necessary bits to provide 2D framebuffer support on
top of VirtIO GPU device as implemented in Qemu. I don't know if any
other implementation of this specific device exists.

Compared to the ramfb driver which already exists in Genode Virtio FB driver
has one major benefit. It allows Qemu window to be dynamically resized at
runtime. The driver will treat this as resolution change and act accordingly.
Ramfb driver can currently only use the hardcoded 1024x768 screen size. Changing
screen resolution might not sound like a big deal, but it is rather useful to
run Genode on Qemu in full screen mode.

2ec9e69fd4 os: Add support for reading VirtIO responses.
Some more advanced devices like VirtIO GPU do expect they can receive
responses to VirtIO commands they issue via VirtIO queue. Such responses
are not sent via a separate device writeable queue. Instead the driver
is expected to queue some additional descriptors and buffers which the
device can then use to provide the reply.

This patch adds support for such write-data-read-response opeartion to
Genode VirtIO::Queue implementation. The implementation is pretty simple
and does not support any fancy features like receiving the response
asynchronously. Instead the operation will use caller provided callback
to wait for the device to process the command. Once this callback
returns the write-data-read-response VirtIO::Queue function will invoke
another callback passing received response as argument.
