1st iteration of volta actually doing something. Process the request, find the best matching rule, and rewrite the request. Without the DB queries, volta was parsing over 750k requests a second. Currently, it's down to 129.5 with 1161 rules in place. Yikes. I may need to re-evaluate some design choices here.

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