change macro name from ADB_NCACHE_MINIMUM to ADB_CACHE_MINIMUM since it's used
...
as a general purpose minimum ttl, and actually set the TTL to the minimum
when re get a negative cache entry.

Make a (perhaps) temporary change to make this build on non-ipv6 aware
...
OSs. It may remain (but not in the present form) since storing ipv6
addresses in the adb makes little sense if you can't use them...

Ignore ipv6 mapped ipv4 addresses.
...
Set a default TTL for type 3 negative cache elements. This is local to
the ADB, and cannot leak to clients, so no specs are violated.
Change a logging level to be less verbose.

Fix a lot of negative caching issues. I believe the code will use

ncache responses from fetches and database lookups correctly now, but
there needs to be a little more cleanup here and there. Bugs exist.

kill name->query_pending, since that bitmask is really represented more

accurately by other means. Reverse the sense of fetch checking from
NO_FETCH_A() and NO_FETCH_AAAA(), etc to NAME_FETCH_A(), NAME_FETCH_AAAA(),
and add address family checks like NO_FETCH_V4() and _V6().
Fix a database dump bug where the A fetches were printed twice rather than
printing the AAAA fetches. Add printing of A6 fetches.
