Postcopy+spice: Pass spice migration data earlier
Spice hooks the migration status changes to figure out when to
transmit information to the new spice server; but the migration
status in postcopy doesn't quite fit - the destination starts
running before the end of the source migration.
It's not a case of hanging off the migration status change to
postcopy-active either, since that happens before we stop the
guest CPU.
Fix it by sending a notify just after sending the device state,
and adding a flag that can be tested by the notify receiver.
Symptom:
spice handover doesn't work with the error:
red_worker.c:11540:display_channel_wait_for_migrate_data: timeout
