Current API requires re-running QEMU to query the information. This
series allows it to be run with the "-machine none" QEMU instance that
is already run by libvirt.
Therein is the reason libvirt isn't using what qemu already has -
spawning multiple qemu instances (one per reported machine type)
multiplied by the number of qemu binaries does not scale well, when
compared to starting a single qemu -machine none, and doing all queries
on that one machine. So the point of this patch is getting us closer to
the point where libvirt can learn accurate cpu model information for
multiple machines all from a single qemu invocation.
