2fe0860ba7 hw_x86_64: Extend inital page tables up to 1 GiB
To avoid future issues with regards to non-existent mappings in the
initial pagetables, extend them to cover the memory range of 2 MiB up to
1 GiB.

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.

Fixes #1624

Bender upstream issue is TUD-OS/morbo#4

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.

Fixes #1618.

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.

bc8a5cbb2a hw: fix CPU-quota bug in Platform_thread

constructor. When called for a user thread, the constructor stated 0
as CPU quota at the Kernel_object instead of its quota input-paramater.

9506c89f88 nova: fix memory leaks / invariant TSCs
- free up kernel memory of empty slabs (if already one empty slab is in
  place)
- free up more page table entries
- handle CPUs with invariant TSCs gracefully

  Genode/Nova running on CPUs without the invariant TSC feature may seem
  to 'hang'. The referenced commit of the nova branch fixes the issue
  for some older Intel CPUs.

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.

785cac7168 decorator: consider partially transparent windows
This patch changes the window manager, the decorator, and the
floating window layouter to propagate the usage of an alpha channel from
the client application to the decorator. This way, the decorator can
paint the decoration elements behind the affected windows, which would
otherwise be skipped.

259b127f96 Polygon drawing and rudimentary 3D routines
This patch adds two new painters located at gems/include/polygon_gfx.
Both painters draw convex polygons with an arbirary number of points.
The shaded-polygon painter interpolates the color and alpha values
whereas the textured-polygon painter applies a texture to the polygon.
The painters are accompanied by simplistic 3D routines located at
gems/include/nano3d/ and a corresponding example (gems/run/nano3d.run).

b4ebefd616 cli_monitor: read subsystem configs from VFS
This patch changes the way how CLI monitor obtains its subsystem
configurations. Originally, this information was provided via the
Genode::config mechanism. But for managing complex scenarios, the config
node becomes very complex. Hence, it is preferrable to have a distinct
file for each subsystem configuration.

The CLI monitor scans the directory '/subsystems' for files ending with
".subsystem". Each file has the same syntax as the formerly used
subsystem nodes.
