c05b26763a qrexec: new communication scheme, agent<->server part
1) Instead of a set of predefined commands, we send MSG_AGENT_TO_SERVER_TRIGGER_CONNECT_EXISTING msg with a parameter (e.g. "org.qubes-os.vm.Filecopy")
defining required action
2) qrexec_daemon just forks qrexec_policy, that will take care of actually
allowing and executing required action
3) after MSG_AGENT_TO_SERVER_TRIGGER_CONNECT_EXISTING, qrexec_agent does not
execute a command - it justs uses already established file descriptors to
send data to/from. Thus, there is no need to use ~/.xxxxxspool - a command line
tool can have direct access to remote fds.

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.

So that evil VM cannot just send flood of exec qfile-daemon requests,
and DoS dom0.

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.
