A future patch is going to wire up qemu active block commit jobs; but as they have similar events and are canceled/pivoted in the same way as block copy jobs, it is easiest to track all bookkeeping for the commit job by reusing the <mirror> element. This patch adds domain XML to track which job was responsible for creating a mirroring situation, and adds a job='copy' attribute to all existing uses of <mirror>. Along the way, it also massages the qemu monitor backend to read the new field in order to generate the correct type of libvirt job (even though it requires a future patch to actually cause a qemu event that can be reported as an active commit). It also prepares to update persistent XML to match changes made to live XML when a copy completes.
