304cb290d9 nic_router: rework quota accounting
* Account all RAM/CAP quota of a session except quota for metadata used in
  core. The latter is considered when asking if a session can afford to make
  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.
* report statistics about session objects and quota if <report stats="yes"
  quota="yes"/> is configured. (default is yes if <report> is present)

bd77bb41df nic_router: improve handling of TCP termination
Like suggested by RFC 2663, reprogram the dissolve timeout of a TCP link
state to 2 times the maximum segment lifetime (by default 1 minute) when
receiving a matching packet with the FIN flag set, or with the ACK flag
set to acknowledge a FIN of the remote side.

Mark a link state as closed (no further reprogramming of the dissolve
timeout) and set the dissolve timeout to 2 times the maximum segment
lifetime when receiving a packet with the RESET flag set.

d6c6549354 nic_router: destroy links on insufficient resource
If the NIC router has insufficient CAP or RAM quota for the creation of
a state object for an interface, it tries to destroy a certain amount of
existing state objects of this interface to free resources. Afterwards,
it retries handling the current packet once. If it does fail again, the
router drops the packet.

364f69edad Xml_generator: fix and test missing '\0'
Ensure that a '\0' always appears at the end of the ouput of the XML
generator.  Previously, exceptions during the Node(...) constructor
might have prevented this. This commit also extends the xml_generator
test to drive a harder test on exceptions in the Xml_generator.

85d589a49c Xml_generator: fix exception handling in Node(...)
When the functor provided to the Node constructor throws an exception,
do revert all changes in reverse order. Previously, the changes made
to the parent node were not considered by the exception handler which
caused unnecessary characters to remain in the out buffer for each
reverted node.

8a9b18e40e Fix for single file VFS servers
The VFS server does not support file-system with one single-file plugin
providing the root. This is because the "leaf_path" is not universally
implemented to handle the path "/". This fix is simply to skip a
"leaf_path" check when opening the path "/".

3c1ea3667d vfs server: avoid nesting of packet processing
This patch addresses a situation where _process_packets was called as a
side effect of watch notification (that was processed during an unlink
RPC operation). This scenario (triggered by the fs_query test)
ultimately ended up in a deadlock. Io/watch reponse handlers should
never re-enter the application logic.

The string ${GENODE_CONFIG_INC} is replaced by the run tool with the

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.

7e08bba25c Cached_fs_rom: fix congestion error
When the cached_fs_rom saturates the packet stream of its File_system
session it will call the session request handler recursively as pending
transfers are completed. This is bad because the content of the XML node
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.

e3005266b6 vfs: no 'handle_io_response()' in regular VFS functions
Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.

With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.

59ac5b10c7 Plugin for importing VFS content
This new vfs_import plugin allows a VFS instance to be populated during
construction using a sub-VFS configured in an '<import>' configuration
node. This allows the ram_fs File_system server to be replaced by the
VFS server by reimplementing the ram_fs 'content' feature.  At the
moment the copying of symlinks is not enabled, and the resources
obtained by the import file-system may not be freed after the import is
finished.

ca042e4e6e Fix VFS notifications for ram file removal
The ram plugin to the VFS must send notifications to watch handles on

the ram_fs server for the sake of notifications.

Move run/fs_report to gems and use the vfs server and the vfs init
plugin in the test.

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"/>
