This series is also available at

The series does several things:
- persists current job and its phase in status xml
- allows safe monitor commands to be run during migration/save/dump jobs
- implements recovery when libvirtd is restarted while a job is active
- consolidates some code and fixes bugs I found when working in the area

The series is not perfect and still needs some corner cases to be fixed but I
think it's better to send the series for review now and add small additional
fixes in the next version(s) instead of waiting for it to be perfect.
