Subject: [PATCH] spice: add 'migrated' flag to spice info
The flag is 'true' when spice migration has completed on the src side.
It is needed for a case where libvirt dies before migration completes
and it misses the event QEVENT_SPICE_MIGRATE_COMPLETED.
When libvirt is restored and queries the migration status, it also needs
to query spice and check if its migration has completed.
