IPv6 tcp proxy success

I feel like an undergraduate computer science student after all of this. I've managed to coax the cacheboy core to support v4/v6 and am using it in the tcpproxy test application.

I've got a modified apachebench speaking IPv6 to tcpproxy, listening on a :8080 IPv6 socket. It then forwards all requests to a thttpd instance running on IPv4.

Tomorrow's job - making sure the squid proxy codebase is still happy with these latest changes, and then preparing for some further testing and the implementation of some unit tests for the comm and inet libraries. Then it back to commercial projects for a few weeks.
