[libvirt] [PATCH 0/2] qemu: Fix deadlocks in autodestroy

After the recent removal of qemu driver locks, implicit driver locks were introduced in places that previously relied on being called from functions that alread had the driver locked. Thus calling anything complex (such as close callbacks) must not be called when the driver is locked...

This series is techincally a v2 but the changes to the previous version are substantial so I'm not marking it as such.
