- The interpretation of wildcard records now matches the description in
  RFC-1034 section 4.3.3. 

Specifically, if there's a wildcard *.x and a record for a.x, 
then a query for y.a.x will *not* be answered using the
wildcard (for a label 'a' and series of labels 'x' and 'y').

This change is required for signed domains, because authentication of
negative responses requires a common understanding between client and
server about the meaning of wildcards.
