[pve-devel] qemu-server : implement pending changes v2

a non-hotpluggage value is in pending until restart, so when a vm is migrated is keep in pending.



Currently, the behaviour is bad, if you add a disk without hotplug, it's registered in vm config file.
Then if you migrate, the target vm will be started with the disk attached, but the memory copy of the source vm don't have any 
reference to this disk, so the migrate will crash at the end.

Is possible that the change a non-hotpluggage value also be migrated with 
the VM?
