cpu: move Qemu[Thread|Cond] setup into common code

Browse source 
Aside from the round robin threads this is all common code. By
moving the halt_cond setup we also no longer need hacks to work around
the race between QOM object creation and thread creation.

It is a little ugly to free stuff up for the round robin thread but
better it deal with its own specialises than making the other
accelerators jump through hoops.
