5ed5fddb7c base/os: remove deprecated APIs
This commit removes APIs that were previously marked as deprecated. This
change has the following implications:

- The use of the global 'env()' accessor is not possible anymore.
- Boolean accessor methods are no longer prefixed with 'is_'. E.g.,
  instead of 'is_valid()', use 'valid()'.
- The last traces of 'Ram_session' are gone now. The 'Env::ram()'
  accessor returns the 'Ram_allocator' interface, which is a subset of
  the 'Pd_session' interface.
- All connection constructors need the 'Env' as argument.
- The 'Reporter' constructor needs an 'Env' argument now because the
  reporter creates a report connection.
- The old overload 'Child_policy::resolve_session_request' that returned
  a 'Service' does not exist anymore.
- The base/printf.h header has been removed, use base/log.h instead.
- The old notion of 'Signal_dispatcher' is gone. Use 'Signal_handler'.
- Transitional headers like os/server.h, cap_session/,
  volatile_object.h, os/attached*_dataspace.h, signal_rpc_dispatcher.h
  have been removed.
- The distinction between 'Thread_state' and 'Thread_state_base' does
  not exist anymore.
- The header cpu_thread/capability.h along with the type definition of
  'Cpu_thread_capability' has been removed. Use the type
  'Thread_capability' define in cpu_session/cpu_session.h instead.
- Several XML utilities (i.e., at os/include/decorator) could be removed
  because their functionality is nowadays covered by util/xml_node.h.
- The 'os/ram_session_guard.h' has been removed.
  Use 'Constrained_ram_allocator' provided by base/ram_allocator.h instead.

69d6145f5a os: don't hide tx_cap from block-session interface
The 'tx_cap' RPC function is only used at session-creation time. For
this reason, it was not listed in the "official" RPC interface in
'block_session.h'. However, this makes the interface more obscure than
it needs to be. So this patch promotes it to a regular RPC function.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.

d3759811b6 os/session_policy: warn if no policy exists
The situation where a 'Session_policy' is constructed for a label with
no matching policy is in almost all cases a configuration problem.
A diagnostic message eases pin-pointing such mistaks. By adding the
message to the 'Session_policy', servers don't need to manually handle
the exception to provide diagnostic information. This simplifies the
server code in many components.

af146e7dcd Remove base/timed_semaphore.h from API
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.

This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.

bf62d6b896 Move timer from os to base repository
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.

Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.

Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.

4f316cffbc init: update state reports on heartbeat responses
Init's state reports are updated whenever an interesting part of init's
internal state changes (e.g., when sessions are established, or when
children are started/removed). However, until now, a change of a skipped
heartbeat counter was not taken as trigger for state-report updates.

In scenarios where no other intersting event happened, the last reported
state did no reflect the current heartbeat state. In particular, when
the last report was issued during the construction of a new child just
before the child became able to respond to heartbeat requests, the stale
report hinted at heartbeat problems that were just an initialization
artifact. This problem became visible on some Qemu platform where the
child startup takes a long time.

The patch tracks the observed skipped-heartbeat counter and triggers a
report whenever the counter value changes.

a2bdcc68c2 Throw exception for invalid packets at packet streams
Some application code is dereferencing the pointer returned by
'packet_content' at packet streams without checking that it is valid.
Throw an exception rather than return a null pointer, except for
zero-length packets, which have somewhat implicit invalid content and
that we believe to be properly handled in all current cases.

The client-side of a packet stream cannot take corrective action if the
server-side is sending packets with invalid content, but the servers
that provide packet streams should catch this exception to detect
misbehaving clients.

c60604062c decorator: improve robustness of window restacking
This patch improves the detection of new appearing top-most windows.
Such a window should prompt the decorator to bring the corresponding
nitpicker view(s) to the front of the view stack. The original
implementation relied on hints provided by the layouter (the 'topped'
attribute). With the patch, the decorator tracks the top-most window by
itself, which improves the robustness.

As a second improvement, the patch defers the destruction of windows to
the point when all other window operations are completed. This hides
intermediate states when replacing one window by another in one step,
which is typical for console-like scenarios. Hence, this patch should
eliminate flickering artifacts when switching from one virtual console
to another.

* Account all RAM/CAP quota of a session except quota for metadata used in

  an operation but it does not get accounted to always be able to pay back all
  quota when a session closes. The general accounting mechanism is moved from
  atop of the allocators down to the level of RAM/RM session operations.

d909715f1b input/ps2: drop fake right-shift scancodes
Seen on X250

Description from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html

  The ten grey keys Insert, Home, PgUp, Delete, End, PgDn, Up, Left,
  Down, Right are supposed to function regardless of the state of Shift
  and NumLock keys. But for an old AT keyboard the keypad keys would
  produce digits when Numlock was on or Shift was down. Therefore, in
  order to fool old programs, fake scancodes are sent: when LShift is
  down, and Insert is pressed, e0 aa e0 52 is sent; upon release of
  Insert e0 d2 e0 2a is sent. In other words, a fake LShift-up and fake
  LShift-down are inserted.

currently being processed will change.

The session request handler can no longer be called directly, but the
"schedule" method will submit a signal to the request handler, and
requests will be processed after the current operation has completed.

4b46abf813 base: rm first-class support for static binaries
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.

Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:

  <route>
    <service name="ROM" unscoped_label="ld.lib.so">
      <parent label="test-platform"/> </service>
  </route>

However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:

  <start name="test-platform" ld="no"/>

3bbeacad20 init: preserve final state of exited children
This is a follow-up patch of "init: avoid too eager child restart". On
each config update of init, init re-applies child-specific configuration
changes. In the case of an already exited child, this re-evaluation
wrongly marked such a child as abandoned because the child's environment
sessions do no longer exist. Abandoning the child, in turn, triggers the
destruction and subseqent restart (because the <start> node of the
configuration still exists). The latter is bad for two reasons.

First, the exit state of the original instance becomes lost. Second, the
restart may have unexpected side effects due to sessions created by the
new instance. I.e., when resizing a partition in sculpt, init would
wrongly restart the gpt-write tool after the tool successfully exited.
This collides with a newly started instance of part_blk/resize2fs, which
now competes with the second gpt-write instance for the exclusive access
of the targeted block device.

The patch prevents init from re-applying configurations to exited
children. The accompanied test case covers the corner case.

2733d3fea5 nic_router: verbose_packet_drop attribute
The log messages covered by verbose_packet_drop were previously
configured by the verbose attribute. This isn't the case anymore. Now,
you can configure them as follows:

! <config verbose_packet_drop="no" ... >
!     <domain verbose_packet_drop="no" ... />
! <config/>

The new attribute determines whether to log each packet drop and the
rational behind it. The <config> value affects all domains without a
<domain> local value.

055862c0eb nic_router: cancel remote ARP on new IP config
When a domain is updated to a new component config, the two criteria for
keeping an ARP waiting state of a remote domain are whether the remote
domain still exists and whether its IP config is still the same. This
means that a domain must also dissolve all of its remote ARP waiting
states if its IP config changes (without an update of the component
config). This wasn't the case until now.

9d8bf1373e Chroot: remove merge policies
The chroot server was conceived to automatically place File_system
sessions into segregated root directories by converting session labels
to paths. If multiple children needed to be grouped under the same path,
a 'merge' policy would truncate the session label before path conversion.
Now that init can rewrite session labels and thus reproduce truncation,
the chroot merge feature is redundant and can be removed.

49a3a0e0d0 nic_router: multiple uplinks
Introduce the uplink tag:

! <config>
!    <uplink label="wifi"  domain="uplink">
!    <uplink label="wired" domain="wired_bridge">
!    <uplink               domain="wired_bridge">
! <config/>

For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.

Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add

! <uplink domain="uplink"/>

or

! <uplink label="[LABEL]" domain="uplink"/>

as direct subtag of the <config> tag.

97ea513122 nic_router: fix pure virtual call in ~Interface()
The interface destructor called pure virtual methods at least when
cancelling ARP- waiting states. The implementations were made by the
deriving classes Session_component respectively Uplink. This led to an
abort of the NIC router as the destruction of the derived class was
already done. A similar problem already occured in the past during the
construction of Interface and was back then solved by introducing a
separate init() method. This commit, however, solved the problem by
making Interface a member of the other classes. Therefore, the init()
method could be removed again. Furthermore, the interface polica could be
moved from Session_component_base to Session_component. The commit also
had to generalize the way the link state of an interface is determined.

b96f0fa2df init: defer immediate restart of abandoned child
While a child is abandoned, we must limit the start of anothers with
the same name. Otherwise - of the child has startup problems - a number
of abandoned children with the same name may queue up. This becomes a
problem whenever the child destruction depends on an asynchronous
service that provides an env session for the children. If the service is
unable to keep up with the session requests (both create and close),
the queue of abandoned children becomes unbounded. Limiting the child
creation rate to one abandoned child per name mitigates this problem.

This isn't sufficient. As soon as one domain becomes invalid we have to
dissolve/destroy this one, deinitialize all other domains again (as they
could contain references to the invalid domain) and retry to initialize
them from the beginning. We proceed with this until we have one run
without a domain becoming invalid. Then we can be sure that the last

ba348b73e2 nic_router: re-use dynamic IPv4 config if possible
When re-configuring the NIC router, determine for each domain if at least one
interface stays with the domain. If a domain fullfills this and has a
dynamic IP config (received via a DHCP client), keep the IP config.

To achieve this, the following changes have been made to the existing NIC
router code:

* Split-up Interface::handle_config into three steps:

  1) Determine for each interface if its domain can keep its IP config or
     or if it has to mark it invalid. This must be done before (re-)attaching
     any interface because during "attach" several decisions are made based on
     the validity of the IP config of corresponding the domain.
     (E.g. whether to participate in sending DHCP DISCOVERs {IP config
     invalid} or whether to participate in sending pending ARP REQUESTs
     {IP config valid} ).

  2) Detach, attach, or re-attach each interface according to the
     configuration. This must be done before re-considering the temporary
     state objects of each interface because the latter might have effects
     on the interfaces of remote domains which must then be in place already.

  3) Re-consider temporary state objects of each interface. (E.g. transport
     layer connection states)

* Re-work IP-config setter in a way that it works as follows:

  1) If the old IP config is valid, let all local interfaces as well as remote
     interfaces that depend on the IP config of the domain detach from the old
     IP config.

  2) Overwrite with new IP config

  3) If the new IP config is valid, let all local interfaces as well as remote
     interfaces that depend on the IP config of the domain attach to the new
     IP config.

fatal. However, this behavior is undesired when init is used in a highly
dynamic yet long-running fashion like sculpt's runtime subsystem. This
change keeps init running despite the error condition, giving the user
the chance to relieve the resource pressure.
