WIP: udp: add ipv6 support

Browse source 
Returning IPv6 peers doesn't really work with UDP. It is not supported by
https://libtorrent.org/udp_tracker_protocol.html. There is a suggestion in
https://web.archive.org/web/20170503181830/http://opentracker.blog.h3q.com/2007/12/28/the-ipv6-situation/
of using action number 4 and returning IPv6 octets just like for IPv4
addresses. Clients seem not to support it very well, but due to a lack of
alternative solutions, it is implemented here
