[libvirt] [PATCH 3/8] qemu: blockjob: Add block job states for abort and pivot operations

[Peter Krempa]

When initiating a pivot or abort of a block job we need to track which
one was initiated. Currently it was done via data stashed in
virDomainDiskDef. Add possibility to track this also together with the
job itself.
