When an authorizeip is returned, a challenge response will be
sent to that ip.
ioquake3: we added a possibility for clients to add a challenge
to their packets, to make it more difficult for malicious servers
to hi-jack client connections.
Also, the auth stuff is completely disabled for com_standalone games
as well as IPv6 connections, since there is no way to use the
v4-only auth server for these new types of connections.
