9efa3ceccf pthreads: use simple Genode::Semaphore as backend
Instead of using Timed_semaphore, we can directly use the simpler
Genode::Semaphore for pthread's 'sem_t' type.

492bd39619 epit timer: raise precision
Previously we used a pretty slow external clock source for the timer. This
resulted in such a low TICS_PER_MS value that the granularity wasn't
sufficient to find a setup with a precision better than 1 second error per
minute. Now we use the so-called High Frequency Reference Clock as input
with TICS_PER_MS=33333 and the timer precision is significantly < 1 second per
minute.

01643ccd94 cpu_quota hw exynos5: raise error tolerance
From our observations we can tell that the error should not exceed 4%.
However, there is no reasonable explanation by now why the test results
are less stable on these platforms. We have tried several things that
did not lead to an explanation or improvement:

  * changing the timing parameters of the scheduler
  * switching off SMP
  * double-checking the speed of userland and kernel timers

227b539193 cpu_quota x86_64: fix RAM quota and stack size
The test threads previously used a stack size independent from the machine
word width. Qemu was previously configured to provide 64Mb of RAM which isn't
sufficient for x86_64.

02ef3d13a3 hw: explain misleading "Quota exceeded"
Upgrading the quota of a PD session on HW always triggers a "Quota

we explain in an in-code comment that the warning is normal.

60ba210a6b hw: reference count capabilities in UTCBs
When capabilities are delegated to components, they are added to the UTCB of the
target thread. Before the thread is able to take out the capability id out of
the UTCB and adapt the user-level capability reference counter, it might happen
that another thread of the same component deletes the same capability because
its user-level reference counter reached zero. If the kernel then destroys the
capability, before the same capability id is taken out of all UTCBs, an
inconsitent view in the component is the result.  To keep an consistent view in
the multi-threading scenario, the kernel now counts how often it puts a
capability into a UTCB. The threads on the other hand hint the kernel when they
took capabilities out of the UTCB, so the kernel can decrement the counter
again. Only when the counter is zero, capabilities can get destructed.

30e129a91b pthread: remove use of private Native_config API
Former Native_config::context_area_virtual_base() was used to identify
the main, which is not desired as the Native_config is rather low-level
(almost private to the base libs). The commit uses a library constructor
to retrieve the main-thread Thread_base pointer, which can be used later
to distinguish main and other threads.

627ecc44d2 Revert "os: reset Audio_out stream prior to calling start"
This reverts commit d8b95c263b.

Some clients might want to fiddle with the clients play position
(e.g. the mixer) within 'Audio_out::start()' and we might reset
it to an old value if we do it afterwards.

6d1e417250 os: reset one packet further in Audio_out stream
Since all Audio_out server components loop over the packet stream
queue it is save to reset the tail position to one after the play
position. We have to do this because we do not know exactly when
the play position changes (i.e. the driver has processed the packet)
and we might end up with a tail position before the current play
position.

d65beb970d dde_linux: KMS-based Intel framebuffer driver (II)
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs

The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax

  <config>
    <connector name="LVDS-11" width="1280" height="800" enabled="true"/>
  </config>

Also, when enabled within the intel framebuffer driver configuration like
the following

  <config buffered="yes"/>

a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.

The  driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows

  <connectors>
    <connector name="LVDS-11" connected="1">
      <mode width="1280" height="800" hz="60"/>
      ...
    </connector>
    ...
  </connectors>

The driver distributes the report only if this is stated within its
configuration, like the following

  <config>
    <report connectors="yes"/>
  </config>
