Introduce a bunch of new public APIs related to backup checkpoints. Checkpoints are modeled heavily after virDomainSnapshotPtr (both represent a point in time of the guest), although a snapshot exists with the intent of rolling back to that state, while a checkpoint exists to make it possible to create an incremental backup at a later time. We may have a future hypervisor that can completely manage checkpoints without libvirt metadata, but the first two planned hypervisors (qemu and test) both always use libvirt for tracking metadata relations between checkpoints, so for now, I've deferred the counterpart of virDomainSnapshotHasMetadata for a separate API addition at a later date if there is ever a need for it.
