IPv6 packet filtering code.
./configure --enable-ipv6 (requires getaddrinfo(3) and getnameinfo(3)). TODO: make it work even without getaddrinfo(3) or getnameinfo(3) (or, tcpdump/configure.in should provide alternative version by AC_REPLACE_FUNCS) TODO: make IPv6 filtering code work by default TODO: make "protochain" friendly with optimization
