Copies heavily from existing virDomainSnapshot handling, regarding
what special cases the generator has to be taught and what overrides
need to be written.
Signed-off-by: Eric Blake <eblake@redhat.com>

Python counterparts to my incremental backup patches. An earlier
version was already reviewed by Dan; the main diff here is the
addition of virDomainSnapshotCreateXML2 handling.

Now that 5.6.0 will have the virDomainCheckpoint API but not virDomainSnapshotCreateXML2, I've reduced this patch down to the portions still relevant and pushed. When we later get around to integrating snapshots and checkpoints, we'll tweak the python bindings again at that time to cover any additional APIs. > > Reviewed-by: Daniel P.
