28ca836e14 vm: support for magic QUBESRPC command 
Previously dom0 had to know full path of qubes_rpc_multiplexer in VM, which can
differ between VMs (eg totally different on Windows). This commit enables dom0
to magic keyword instead of full path.

11c1cb0aa2 qrexec: temporarily disable auto executing domains upon rpc request 
There are two problems with qvm-run -a:
1) even with -q flag, it spits to stdout (actually, "xl create" does it), and
this garbage is received by rpc client
2) even with -q flag, it steals input (actually, "qrexec ... wait for session")

These two can be manually fixed (by passing /dev/null appropriately); hovewer,
this is prone to disaster if qvm-run is enhanced/broken later.

We could do
if is_domain_running() ; then
	run qrexec client
else
	qvm-run -a domain true </dev/null >/dev/null
	run qrexec client
fi
which looks safer; but is_domain_running() is a bit expensive even in "running"
case - we need to xl_context.list_domains anyway.

Gotta decide on one of these.

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.

e7d2eefecd qrexec: fix stdout flush on process exit 
In case a child of qrexec_daemon has exited and there is still data in its
stdout pipe, we need to flush it to the peer. Previously, the case when the
peer is blocked was not handled; it is now. The bug impact was premature EOF.
