I shouldn't have used the term "namespace". I realize now it's confusing,
sorry.

Just to be clear, all servers are stored in one big list. The Q3A servers are
not different, they are just using "Quake3Arena" as their "gamename". In other
words, there's no difference between declaring a server using the Q3A master
protocol, and declaring it using the DP master protocol with "Quake3Arena" as
its "gamename".

I wouldn't really see the point of removing the vanilla Q3A master protocol. It
wouldn't simplify the code significantly, and IOQ3 would lose interoperability
with other tools and master servers.

Anyway, the point is: indeed, IOQ3 itself doesn't need the DP protocol. But if
a standalone game based on IOQ3 doesn't want to receive IP addresses of Q3
servers from the masters (and doesn't want to change the network protocol
number just for that purpose), it will need to send a custom gamename. And the
only way to do that is to use the DP master protocol.

If it's not already in the IOQ3 code base, standalone games will have to patch
the code themselves. So the idea here is to put the code as an option into the
IOQ3 trunk to avoid redundant work.
