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>.
