Clean up redundant parser actions via preprocessor macros, add a hostname->tld extractor for doing tld "wildcard" queries. Stop tracking 'parser.c' completely.

Add some more Makefile hacks to get things consistently building across OSX, FreeBSD, and Ubuntu. (There may be more later, but I'll deal with those then.)
