This series makes use of the chardev fd passing arriving in QEMU 2.12
to get rid of the startup race wrt opening the QEMU monitor.

The same thing benefits the agent too but I've not tackled that yet.

Daniel P. Berrangé (3):
  qemu: probe for -chardev 'fd' parameter for FD passing
  qemu: support passing pre-opened UNIX socket listen FD
  qemu: don't retry connect() if doing FD passing
