Recent patch [1] renames the save_live_complete_precopy handler to
save_complete, as the machine is not live in most cases when this
handler is executed. The same is true also for
save_live_complete_precopy_thread, therefore this patch removes the

Could be some future users, that would benefit from separate hooks for
precopy and postcopy?
In case we are going to drop it, I think the '_precopy' suffix could be
dropped too, as the handler would be used for postcopy too.

theVIRTIO_MEM_F_PERSISTENT_SUSPEND feature to the guest kernel driver
when suspending is possible in QEMU (currently only x86).

device can access the reset type in the hold
phase. The last patch of the series implements the final support in the
hold phase of the virtio-mem reset callback and exposes
VIRTIO_MEM_F_PERSISTENT_SUSPEND to the kernel.
