virt: Inform Engine about switching to post-copy

Engine must be informed when a migration switches to post-copy mode (to
know where to get further events and stats from).  We use status event
for that purpose.  We report paused state for VMs in post-copy migration
mode on the source, so we must distinguish between paused state in
post-copy migration and paused state for other reasons.  We use
pauseCode for that purpose.
