In preparation for making RS support IPv6. NB: This breaks the build of retroshare-gui, as the sockaddr_storage_xxx fns are only defined as prototypes for now. All the aux libraries like udp / stun / tcponudp / dht have still to be converted. These changes will probably break various things and need to be tested thoroughly. git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.6-initdev@6735 b45a01b8-16f6-495d-af2f-9b41ad6348cc
