The Xml_generator is extended by overloads for bool as well as signed
and unsigned int, long, and long long.

98a4cb27b2 decorator_stress: explicitly generate long values
Explicitly cast floats to long as we currently do not plan to support
float in Xml_generator and previously the value was implicitly casted to
long anyway.

dc17e16897 signal: cleanup allocations / reset globals in test
I conserve these cleanups to enable the looped execution of all test
functions as I did to hunt a bug. The loop can easily be added to

cebef2bda3 noux: make copy of input fds in SYSCALL_SELECT
Executing the system call will change the input fds as a side-effect
because the select_in.fds and select_out.fds structure are part of a
union. Since the original select_in.fds content is needed afterwards
make a copy instead of using a reference.

2316937e58 hw: remove main thread's initial UTCB from vm area
The main thread's UTCB, used during bootstrap of the main thread before
it allocates its context area, needs to be outside the virtual memory
area controlled by the RM session, because it is needed before the main
thread can access its RM session.

23f9761297 base: minimize critical section in Semaphore::up
When unblocking a thread in Semaphore::up() while holding the fifo meta-data
lock, it might happen that the lock holder gets destroyed by the one it was
unblocking. This happened for instance in the pthread test in the past, where
thread destruction was synchronized via a semaphore. There is no need to hold
the lock during the unblock operation, so we should do it outside the critical
section.

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

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.
