1d24ef9d1a 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.

fb71bf968c 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.

af7fefa73f qrexec: handle buffered writes correctly 
In case when we have a buffered write, always append to the
buffer, even if the pipe happens to be writable now. If not,
in case of certain tight race we might end up writing buffered data in
wrong order.

d40fb3a2e1 Fifo semantics is hard to get right. 
Finally: we need to close the command pipe at EOF.

15bab70eae Handle pipe io in qrexec_agent properly 
Don't reopen pipe after each read - no need, and it could lose events.

769eedd33a Make qrexec_client wait for its local child before exiting 
If we do not wait and exit imemdiately, qrexec_daemon will decrease
the children count and continue spawning processes, while e.g.
qfile-daemon still waits for kdialog - so dom0 will be DoSed by
multiple processes.

27cfd6111a qrexec_daemon limits the number of its children 
So that evil VM cannot just send flood of exec qfile-daemon requests,
and DoS dom0.

a195f436b7 In qfile-unpacker, set perms on the directory only on second pass. 
It solves problem with transferring r.x directory. Originally, it
would fail when creating files in the directory (as it is not
writable). Now, we will create it rwx, create files in it, and fix
perms and utimes on the second pass.

f1a7df6e95 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.

8f90623661 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).
