Each interface has a single pointer to a filterref object. That

The parser had previously just silently overwritten earlier filterrefs
when a new one was encountered, so the interface was left with
whichever was the last filterref in the xml, ignoring all the
others. This patch logs an error when it sees more than one filterref.
