The server answers each player's WebRTC offer (signaled over the socket) with a
connection of its own: frames go on a lossy channel, everything else on a
reliable one, and the socket carries them until both open or where UDP is
blocked. The client's Net now holds one link to the server instead of one per
player. WebRTC takes UDP 47810-47899 by default, set on the command line.

The server now runs every lobby's sandbox and queued games as rooms, stepped at
the tick rate on one thread. Players send controls ahead of time, late ones repeat
their last, and everyone in a room gets back the controls it played, its events
and checksums. Games start from sandbox queues, players return when they leave,
and play-again moves them to a fresh room. Protocol version 3.
