Hi, Andrew.

I don't get why one would care about removing all listeners that match.
 I can't think of a scenario where it would make sense to add more than
one listener/pvt pair.  To me, if someone does that, it's a bug.  I'd be
fine with the name still singular and it removing the first matching
listener/pvt pair:

  void errlogRemoveListener(listener *, void *);
