f996697fd5 VFS: local ram_fs instances
Move FS Node implementations from server/ram_fs to include/ram_fs.
Support embedded ram_fs instances in VFS configurations using <ram/>.
Add 'no space' handling to VFS symlink ops.

2f1db06deb rump_fs/fuse_fs/lx_fs/ram_fs: symlink fixup
Allow symlinks to be passed to the read and write file system utilities.

Disallow writes to symlinks with offsets in file system servers, this is
to ensure that writing the target of a symlink is an atomic operation.

b60f28bee9 run/load/tftp: detect bad directory
If a user has e.g. /tftpboot/x86 as directory and configures
base_dir=/tftboot and offset_dir=/x86, this leads to bad behavior
as the load module creates a symlink

/tftpboot/x86/<builddir> -> <absolut_builddir>

in this case instead of the desired

/tftpboot/x86 -> <absolut_builddir>

Furthermore, the module works on

/tftpboot/x86/config-00-00-00-00-00-00

and

/tftpboot/x86/<builddir>/config-00-00-00-00-00-00

afterwards, which looks bad too. As there is no warning at all, this can
be hard to debug. The commit adds an appropriate check with error message and
exit -1 on an existing directory.

fe4e0702d4 base: contain chunk_size heap consumption
Increase internal chunk size of heap only if an allocation succeeded
beforehand. Otherwise the chunk size increases with every unsuccessful
invocation and a upgrade of the used ram session will be insufficient and of
no use at all.

73f9bb73cd init: don't block for resource upgrades
If some sessions run out of memory in init, resource requests will be issued
to core, which it never will satisfy. Setting some default signal handler
avoids that the default implementation will block init for ever.

ba18ab7225 run/cpu_quota: raise measurement precision further
Three things were done:

* Timouts are measured in an asynchronous way to be able to start counters
  after the potentially expensive RPC that starts the timeout.
* Timeouts were increased from 45 and 15 seconds to 60 and 20 seconds
  because at least on Arndale, results were not stable enough.
* Counting is done on 'unsigned long long' instead of 'unsigned' because
  with the higher timeouts, overflows occured.

3c49113e64 timer & hw_arndale: don't use any float ops
The timer driver previously used floating point operations to translate us to
tics and vice versa. This isn't necessary as the rounding error isn't critical
for the given values but expensive which should be avoided in a code path that
must be executed pretty frequent with high priority.

bc827787f4 bender: unconditionally relocate all boot modules
If just one multiboot kernel module was loaded after bender, the
relocation was skipped before. This resulted in a corrupt binary image
on ELF loading if the regions of the boot module and the final program
overlap. Now, all modules are copied below 2 GiB (and out of the way)
before ELF loading.

0f05fa6fd4 base: resolve dead lock in weak pointer templates
This commit eliminates the mutual interlaced taking of destruction lock,
list lock and weak pointer locks that could lead to a dead-lock situation
when a lock pointer was tried to construct while a weak object is in
destruction progress.
Now, all weak pointers are invalidated and dequeued at the very
beginning of the weak object's destruction. Moreover, before a weak pointer
gets invalidated during destruction of a weak object, it gets dequeued, and
the list lock is freed again to avoid the former dead-lock.

7e40f5f587 base: use proper Cpu_session when tracing threads
Up to now it was not possible to trace threads that use a different
Cpu_session rather than env()->cpu_session() (as done by VirtualBox).
This problem is now solved by setting the Cpu_session explicitly when
creating the event logger and attaching the trace control area when
creating the thread.

eaf4150c7b cpu_quota.run: support X86
The timer driver on X86 needs CPU quota with highest priority as it
frequently has to interrupt the counters to update the PIT.
On ARM this makes no difference in the test results as ARM timer
drivers, once configured, can sleep until the end of the timeouts.
On X86 we raise the error tolerance to 2% (default 1%) to compensate
the error caused by the timer.

e6995ecad7 sdl: sync tail pointer in SDL_Audio backend
SDL uses the Audio_out session in streaming fashion. For this reason
the audio might be played with delay of at most the queue size. To
mitigate the effect we synchronize the tail pointer to the current play
pointer when the PlayAudio() function is called by SDL for the first
time.

3c0517fe1f init: use binary name as ROM label
Init used to specify the unique child name as session label when
requesting the binary image of a dynamically linked child. The actual
module name was propagated as "filename" session argument. Since we want
to move towards the sole use of the session label, which can be taken
into account for the session routing, the module name should always be
the last part of a ROM session label.
