Re: [libvirt] [PATCH v4 02/12] qemu: Convert jobInfo stats into a union

Convert the stats field in _qemuDomainJobInfo to be a union. This will allow for the collection of various different types of stats in the same field. While doing this, also change the name of the field from @stats to @migStats to make it easier to find. When starting the async job that will end up being used for stats, set the @statsType value appropriately. The @mirrorStats are special and are used with @migStats in order to generate the returned job stats for a migration. Using the NONE should avoid the possibility that some random async job would try to return stats for migration even though a migration is not in progress. For now a migration and a save job will use the same statsType Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt;
