qrexec: add option to wait for VM-VM connection termination 
Normally when qrexec-client setup VM-VM connection it exits
immediatelly. But it may be useful to wait for the connection to
terminate - for example to cleanup DispVM.

qrexec-daemon (the one that allocated vchan port) do receive such
notification, so expose such option to qrexec-client.

b07475efea qrexec: make the log writable by qubes group 
Otherwise if VM was started as root, it will never start as normal user
again.

d031126737 Add "--" to separate options from (untrusted) non-options arguments 
This will prevent passing an option instead of command (qvm-run) /
domain name (qrexec-policy). In both cases when VM tries to pass some
option it would fail because missing argument then - VM can not pass
additional arguments, so if one act as an option, one argument will be
missing).

7bdf7b3f36 use domain name in error messages and log file name

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.

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.
