'block_for_signal' and 'pending_signal' now set pending flag in signal context
in order to determine pending signal. The context list is also used by the
'Signal_receiver' during destruction.

Instead of just red messages in the log and a hanging caller, the issuer
may respond to it - e.g. a noux bash shell will show an error and is
afterwards still usable.

Accidentally removed by #1658. We need to make the cleanup call for server
objects - otherwise we may get in capability identifier re-use trouble.

The notion of a channel is shared by the mixer backend as well as the
frontend. To make dealing with reports between those easier move the
Channel definition to a global header.

This effectively enables configuring builds with -O0 for rump sources.
Note, if the build directory is not clean, at least var/libcache/rump*
should be removed before building with changed etc/tools.conf.
The test performs several rounds of write-read cycles with the following
configuration attributes in a <write-read> config node
rounds determines the number of rounds (default is 4)
size determines the number of bytes written/read in one round
(default is 4 MiB)
buffer_size determines the size of the write-read buffer
(default is 32 KiB)
In one round the test writes and reads "size/buffer_size" times
from/into a buffer_size'd buffer.

Instructions:
1. Create a file in terminal one in the 'ram' directory
! echo "test" > ram/test
2. Second terminal
! tail -f ram/test
3. First terminal
! echo "Meaningless output" >> ram/test
4. Observe second terminal
The pthread object for the main thread initializes its 'Thread_base' base
class part with a reference to the 'Thread_base' object of the Genode main
thread. Therefore the pthread object for the main thread should never be
destroyed, as this would also destroy the Genode 'Thread_base' object.

Trapping rdtsc creates a huge load in some guests, e.g. Windows 8.1,
that use this instruction very frequently. This influences audio
playback/recording in a bad way (distorted sounds, …). As a interim
solution disable the virtualization of rdtsc completely. As long
as each guest VM runs on its own CPU core it should be fine as there
should not be that much interference (TSC warping).
That being said, TSC offsetting as well as adjusting within vbox have to
be evaluated.
Fixes#1768.
