Peter Krempa aac5899db9 qemu: Introduce helper functions for passing FDs to qemu
The existing helpers we have are very clumsy and there's no integration
with the monitor.

This patch introduces new helpers to bridge the gap and simplify handing
of fdsets and classic FD passing when generating commandline/hotplug
arguments.
