Generating a response when the qname matches a wildcard and the type
doesn't exist didn't work; the NXT name was improperly expanded and the
wildcard proof was omitted.

Michael Graff ab7ce5eb6e detach from quota in an error case. I don't know if this is strictly needed, 
but it makes sense.  It is probably done later as well, but all places
check for the pointer != NULL, so we'll be ok.

DNSSEC wildcard negative proof responses were longer than necessary in
some cases; the existence of a node for which the qname is a subdomain
obscures all shallower wildcards.

That is, query for y.x.foo.com.  If the response contains an NXT
at x.foo.com, it's not necessary to prove that there's no wildcard at
*.foo.com, since it wouldn't be matched anyway.

Mark Andrews 240a5d160a When returning a delegation from the cache and the DO bit is set, always 
try to add a DS.  The test for the existence of the sigrdataset was bogus
and crashed the server.

to reproduce:
 - create a signed parent & child zone
 - query a recursive server for the ns record of the child
 - query the recursive server for a name in the child with +norec
