ce57319e4b nic_router: bind uplink session lifetime to domain
Normally, the NIC sessions are independent from the domain tags.
However, by now the uplink session, in contrast to the sessions of the
other domains, is still not a server but a client. This means that only
the NIC router itself can decide when to open and close uplink sessions
and how many. Thus, with this commit, we break with the pattern that
session lifetime is independent from domains by letting the NIC router
create the uplink session when the uplink domain appears and close the
session when the domain disappears.

7085640f05 nic_router: remove 'mac_first' attribute
Since the router MAC is allocated like the donwlink MACs it can't happen
anymore that these MACs clash, for instance due to nested routers. Thus,
the range of the MAC allocators of nested routers must not be exclusive
anymore which deprecates the 'mac_first' configuration attribute.

e83f095fd2 nic_router: downlinks use own router MAC address
Allocate a virtual MAC address at runtime that is used as router
Ethernet-identity for all downlink domains. This makes the downlink
domains independent from the uplink session.

41dbad13e4 nic_router/nic_bridge: re-work Mac_allocator
The old MAC allocator had several drawbacks:

* the address base was a public static that could and must have been written
  directly from outside the class
* the in-use-flag array was based on unsigned values consuming 4 bytes each
  for only one bit of information
* it was a public header that we actually don't want to expose to all
  components but only to the few networking components
* it used the not-so-safe bit notation for integer members of GCC

The new version fixes all these drawbacks.

980f3e9c5c net: use Size_guard for packet-data accessors
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.

This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.

Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.

The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).

11a297b557 net: consider tail of Ethernet frame
The Ethernet payload may be followed by padding of variable length and
the FCS (Frame Check Sequence). Thus, we should consider the value
"Ethernet-frame size minus Ethernet-header size" to be only the maximum
size of the encapsulated IP packet. But until now, we considered it to
be also the actual size of the encapsulated IP packet. This commit fixes
the problem for all affected components of the Genode base-repository.

1f1302e185 terminal: use VFS-based font handling
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.

To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.

6a12a6b4ba vfs: reduce ROM-update rate Rom_file_system::stat
The 'stat' method is called for all paths, not just the specific file
system node of the ROM module. The ROM update is needed only in the
latter case.

Otherwise, when always updating the ROM on stat, stat calls on the VFS
become very expensive in the presence of a mounted ROM module if the ROM
is obtained from fs_rom (which re-watches the file and all its
individual path elements whenever the 'update' RPC function is called).

9d233b73a3 nitpicker: improve 'Session::focus' handling
Nitpicker's 'Session:focus' call used to trigger a one-off focus change
at call time. This focus change did not pass the same code paths as a
focus change triggered by a "focus" ROM update, which led to
inconsistencies.

This patch changes the implementation of 'Session::focus' such that the
relationship of the caller and the focused session is preserved after
call time. Whenever the calling session is focused in the future, the
specified session will receive the focus instead. So 'Session::focus'
represents no longer a single operation but propagates the information
about the inter-session relationship. This information is taken into
account whenever the focus is evaluated regardless of how the change is
triggered.

This makes the focus handling in scenarios like the window manager more
robust.

93a0c66589 timeout: do not handle timeouts while scheduling
To handle all pending timeouts in the context of scheduling a timeout
was only necessary because the Timeout framework once made use of the
Alarm framework. The method Alarm_scheduler::schedule_absolute took an
absolute deadline as argument and we couldn't change this beause the
Alarm framework was also used without the Timeout framework. We had to
calculate this absolute deadline with the now time of the Timeout
framework but the Alarm framework has its own now time that is always a
bit behind the one of the Timeout framework. This lead to bad decisisons
when finding the right position for the new timeout. Now, we can call
schedule_absolute with a relative duration and thereby fix the problem.

When we schedule an absolute timeout without considering the small time
difference, the end-time for the timeout that is calculated using the
local time value is also smaller than the expected end-time. This can
also lead to directly triggering timeouts that should have triggered
with a certain delay.

As it is not trivial to update the local time value while scheduling a
timeout _without_ calling other timeout handlers, we simply raise the
duration of the new timeout by the age of the local time value.

deadlines still in place.

bfb96536da timeout: _setup_alarm calculates deadline itself
Instead of taking the absolute deadline of a timeout as argument from
outside (where it is calculated with a freshly requested now time), we
now take a relative duration as argument and calculate the deadline with
the scheduler-internal now time (which can be a little bit outdated).
This enables us to schedule timeouts without updating the internal now time
and thereby handle all pending timeouts.

38dbd59d8a timeout: become independent of the Alarm framework
Integrate the code of the Alarm framework directly into the Timeout
framework.  The former Alarm-framework methods are all private to the
corresponding classes of the Timeout framework and get prefixed with
'_alarm__'. The latter avoids name clashes and makes it easier to
simplify the code later.

8c7bbdecdf nic_router: conform log in Domain
In the domain class there were several places where output was generated
not conforming to the typical output format of the router ("[domain]
event: parameters").

87eb23f562 nic_router: fix uncaught Domain_tree::No_match
When having an interface that yet is not attached to a domain, then a new
configuration comes in and the interface receives a domain name (via the
policy tag) but the corresponding domain doesn't exist, an exception
Domain_tree::No_match is thrown but was not caught and handled until now.

54b10b1b38 nic_router: forward ICMP dst unreachable messages
This follows the guidelines in RFC 5508 to enable forwarding of ICMP
"Destination Unreachable" that correspond to an existing link state in
the NIC router. It also serves as blueprint for forwarding ICMP error
messages in general (They are merely not enabled because we don't test
them).

6a988749a1 nic_router: print packet info before sending it
By now, the 'verbose packets' output when sending packets was printed after
finish sending the packet. This makes following the packet flow harder if you
have multiple components that print such information.

168407a40a nic_router: config attribute 'mac_first'
The mac_first attribute tells the MAC-address allocator of the router
from which MAC address to start allocating. This is useful, for
instance, if you have nested nic_routers. In this case, identical
MAC-allocator settings have led to name clashes in the past, so, you
want to be able to configure them differently.

7b3343c2dc nic_router: NAPT for ICMP echo messages
This follows the guidelines in RFC 5508 to enable ICMP echo through a NAPT
channel of the NIC router. It serves also as blueprint for ICMP queries in
general (they are merely not enabled because we don't test them by now).

9b936dd120 nic_router: packet verbose at detached interfaces
The 'verbose packets' output previously was not generated for Interfaces
without a domain. But this is desirable as the router nonetheless
receives packets at such interfaces. This is now fixed and such output
is simply prefixed with a "[?]" denoting that the interface has no
domain.

4dc8f6dca4 nic_router: fix missing IPv4.ECN initialization
We missed to zero-out the ECN field in IPv4 packets. We don't use the ECN
field but there might be old data left in the packet RAM allocated by the
NIC packet streams. If we don't zero-out ECN it might leak old data.

9c6b720ec1 Notification support for the VFS library
Add a new 'Vfs_watch_handle' type to the VFS interface. This handle type
will pass a handle context up through the I/O handler to the application
when a notification event occurs.

Watch support implemented for RAM and File_system plugins, all other
file-systems return WATCH_ERR_STATIC by default.

Test at run/fs_rom_update_ram and run/fs_rom_update_fs.
