79abec9038 qrexec: fix deadlock in qrexec-client 
When VM-VM qrexec service is called, two qrexec-clients are connected in
dom0. If both VMs are sending data simultaneously it can happen that
both qrexec-client processes will call write(2) and none of them will be
reading -> deadlock.
Solve it by handling I/O in two separate threads (one for reading from
VM, another for writing), at any time qrexec-client is ready to accept
data from either direction.

f77e2d656d qrexec: remove dialog box in case of connect timeout (#790) 
Instead exit with failure (keeping child process for further connect
retries) and let the core/user decide what to do.

771be64912 qrexec-daemon: fix read underflow when the last fd goes 
If no remaining fd is alive in the list, the loop breaks when i
is negative, but by then clients[-1] would have been dereferenced.

5e4e1fe6ac qrexec-daemon: fix pathological break-out-of-wait-loop 
If the timeout is 1, attempting to retry would not actually retry,
since i would be incremented just after being reset to 0, and would
thus break out of the loop.

97c7c97420 qrexec-policy: warn if some data is ignored 
Something like vm1 vm2 allow, user=foo would be 4 items,
and the user part would be ignored by the parser.
It might or might not be better to error out instead of
just warning, though...

19e7663928 qrexec-daemon: optionally don't wait for connection to the VM 
Will be used to keep qrexec-daemon running in the background even if no
qrexec-agent installed (yet). Specifically to give the VM a chance to
inform about just installed agent.
