Maybe it's worth filtering on whether a filter is just references to
other filters, contains rules, or contains both.  But for that to be
useful, it would also be nice to have an API where, given an individual
virNWFilterPtr, we can then return a list of all other virNWFilterPtr
that were pulled in by reference (that is, similar to snapshots, have an
API sufficiently powerful to reconstruct the tree of filter references).
 So I'm okay with this version going in with no flag support for now.
