Instead of using the 'alloc()' method to allocate new packets use
the 'next()' method with the previous packet. This is needed because
the last audio stack changes broke the semantics assumed by 'alloc()'.
We now keep track of the already queued packets by hand.
Fixes#1827.
Use kernel branch which is more accurate in accounting memory, which avoids
kernel messages of following form:
[0] warning: insufficient resources ...
Fixes#1830
Enable automatic build of Muen system image by adding the image/muen run
script to RUN_OPT. Also specify --image-muen parameters with explanatory
comments.
Note: The ISO image is not built by default anymore.
The script takes the following RUN_OPT parameters:
--image-muen-external-build Muen system is built automatically or externally
--image-muen-system Muen system policy
--image-muen-components Muen system components
--image-muen-hardware Muen hardware platform
--image-muen-gnat-path Path to GNAT toolchain
--image-muen-spark-path Path to SPARK toolchain
Because a check for the TEST_WRITE configuration was missing as condition for a
packet submit, the test caused unwanted write access to the device.

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.
Issue #1819
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.
Fixes#1809.
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.
Fix#1804
This patch adds diagnostic messages during the label-policy application,
if no policy for the session label was found or if the domain configured
in the policy node does not exist.
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.
Fix#1333
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.
Fixes#1805
