When the block copy operation is started with a reused external file in incremental mode libvirt will need to open and insert the backing chain for that file into qemu (in -blockdev mode). This means that we'll need to track the backing chain and metadata such as node names for the full chain of <mirror>. This patch invokes the full backing chain formatter and parser for <mirror> so that the chain can be kept with <mirror>.
