babe1d1026 acpi: amend handling MMIO regions for ACPI tables
The handling of MMIO regions now supports more pathological cases with
weird cross references. Also, MMIO regions are releases after the
parsing is done.

0f47ac958b log/serial: handle spurious EOF
While booting up, some devices send garbage over the serial connection.
This can result in an unexpected EOF event within expect(1). A filter
program may be specified with '--log-serial-filter' to circumvent this
problem. Then, the output of the serial program is piped through
the filter, which may sanitize the character stream.

Fixes #1395.

3a40c27c26 hw_vea9x4: quickfix slow RAM access
Setting the ACTLR.SMP bit also without SMP support fastens RAM access
significantly. A proper solution would implement SMP support which must enable
the bit anyway.

467eee07a6 run: increase tcl buffer for run_genode_until
and move it close to run_genode_until implementation.
Somehow the "match_max -d" gets ignored if it is to far away and some
our run scripts fails because the buffer contains not all information
(seen for affinity.run on a 8 core machine)

00167aec14 hw: activate perf-counter by default
This is needed at least by rump_ext2.run as it uses the perf-counter
in the jitterentropy-lib. On other platforms the perf-counter gets enabled
by the kernel by default. However, on HW, we keep the specifier to allow users
to disable it easily (e.g. for security reasons).

a838b6a657 noux: add local nanosleep(2) and sleep(3)
Up to now Noux used the libc sleep functions, which actually is not
possible because the _nanosleep() function implemented by our libc
creates a new thread to handle the timeout. Noux childs may have
only one thread, e.g., the main thread, though. To fix this issue
sleeping is now handled directly by Noux. It is implemented by calling
select(2) with a timeout. This fix is needed for mutt(1), which calls
sleep when it prints a notification for the user.

0ac039fad7 L4Linux: make ballooning driver configureable
To circumvent compilation errors with the older L4Android Linux kernel
version, the ballooning driver is included in the more recent L4Linux
kernel only. Moreover, to be able to maintain L4Android / L4Linux in a more
convenient way, e.g. to apply patches valid for both versions, we use
the same git clone that is used for L4Linux instead of using the upstream
L4Android version by applying patches.

6d2c697da1 lxip: Fix timeout handling for 'schedule_timeout'
Up until now 'schedule_timeout' did only wait for the next signal to occur.
However, we might run into situations where there won't occur signals for longer
periods of time. Therefore, we took care of the respective timeout handling.

This commit also adds Genode's tracing support
