This is to delete a snapshot object atomically, the API accepts

Add a new flag VIR_DOMAIN_SNAPSHOT_DELETE_CURRENT, others are same.

This flag doesn't specify how to delete a snapshot, it says which one to
delete. These flags are shared with virDomainSnapshotDelete, but both Delete
and DeleteByName would do the same thing with this flag (if you implemented it
in the first one too).
I think it would be nicer to assume SnapshotDeleteByName with a NULL name
means current snapshot.
Sorry, it is so late to respond.
I agree what you pointed out above, the DELETE_CURRENT didn't make
itself clear.
For SnapshotDeleteByNam(), it accepts NULL as name, so it could be
simpler to represent current snapshot object.
I will change it in v2.
Thanks.
