Is this as efficient though?  Discarding all snapshots could be 
reasonably expected to be O(1).  If you say this is not a common 
operation, that's fine of course.

Even without special casing the base image, I'm a bit uneasy that a 
virDomainSnapshot* API touches the base image.  What do you think about 
leaving the merge operation as a virDomain* API, e.g. virDomainRebase?
