The mirror block job is mainly used for two different scenarios: Mirroring to an otherwise unused, independent target node, or for active commit where the target node is part of the backing chain of the source. Similarly to the commit block job patch, we need to insert a new filter node to keep the permissions correct during active commit. Note that one change this implies is that job->blk points to mirror_top_bs as its root now, and mirror_top_bs (rather than the actual source node) contains the bs->job pointer. This requires qemu-img commit to get the job by name now rather than just taking bs->job.
