You can already do:

  ss = virDomainSnapshotLookupByName(dom, name);
  virDomainSnapshotDelete(ss, flags);

and your patch is just enabling:

  virDomainSnapshotDeleteByName(dom, name, flags);

I really don't see any reason to add this new API, as it does not offer
any functionality that was not already available.

NACK unless there's better justification of why this is needed.
