Rather than allowing a leaky abstraction where multiple drivers have to open-code operations that update the relations in a virDomainSnapshotObjList, it is better to add accessor functions so that updates to relations are maintained closer to the internals. This patch finishes the job started in the previous patch, by getting rid of all direct access to nchildren, first_child, or sibling outside of the lowest level functions, making it easier to refactor later on. The lone new caller to virDomainSnapshotObjListSize() checks for a return != 0, because it wants to handles errors (-1, only possible if the hash table wasn't allocated) and existing snapshots (> 0) in the same manner; we can drop the check for a current snapshot on the grounds that there shouldn't be one if there are no snapshots.
