IPv6 causes problems (master server and game)

[lxkurko]

If IPv6 is enabled for the game server and the master server (only HTTP master server tested), the game server gets registered with IPv6 address. However, the master server doesn't apparently handle IPv6 address format correctly, and error messages like this appear in the game console:

H: Menu_SvrList_RefreshServer(): cannot parse server addr xxxx:yyyy:zzzz:q:23400

I did some packet analysis and it seems that the master server gives a truncated address as shown above, and the port specification seems to be wrong too (IPv6 port should be marked with square brackets). I'm not sure how the game would work if it got a correctly formatted IPv6 address from the master server. However, entering an IPv6 address manually doesn't seem to work as the address field has a limit for the address length.

IPv6 was disabled for HTTP masterservers in cde6571 as a workaround. I will add proper IPv6 support sometime later.

I spotted these errors when using 0.58 rc5. Local network was IPv4 only.

It's just a log, it should not impact any functionality. I'll remove the 'error' tag.
