When the guest unplugs the disk frontend libvirt is responsible for deleting the backend. Since a blockjob may still have a reference to the backing chain when it is running we'll have to store the metadata for the unplugged disk for future reference. This patch adds 'chain' and 'mirrorChain' fields to 'qemuBlockJobData' to keep them around with the job along with status XML machinery and tests. Later patches will then add code to change the ownership of the chain when unplugging the disk backend.
