IPv6 support for LibVNCServer, part one: accept IPv4 and IPv6 connections.

This uses a separate-socket approach since there are systems that do not
support dual binding sockets under *any* circumstances, for instance
OpenBSD. Using separate sockets for IPv4 and IPv6 is thus more portable
than having a v6 socket handle v4 connections as well.
