[libvirt] [PATCH 00/19] Rollback migration when libvirtd restarts

This series is also available at https://gitorious.org/~jirka/libvirt/jirka-staging/commits/migration-reco... 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.
