qrexec: when forgetting about a client/process, flush buffered data
...
We need to spawn a child to take care of buffered data flushing, if there
is any. Expensive, but should be needed rarely.

qrexec_agent: when receiving close from daemon, check buffered data
...
We need to wait for buffer flush, so that buffered data is not lost,
and only then close pipe to the child.

Handle pipe io in qrexec_agent properly
...
Don't reopen pipe after each read - no need, and it could lose events.

Implemented mechanism to trigger predefined execution in dom0.
...
Processes in AppVM can ask qrexec-agent to send a
MSG_AGENT_TO_SERVER_TRIGGER_EXEC message to qrexec-daemon.
The latter will execute predefined program. It is useful for
the purpose of file copy; the predefined program will create
a connected qfile-daemon<->qfile-agent pair.

Add ability to execute command without help of /bin/su
...
It is important, if the program closes stdout, but does not exit.
Then, qrexec_agent does not see EOF (because su still holds the
file descriptor).
