Connection Protocol
This is the network info/connection protocol. It is used to find Quake servers, get info about them, and connect to them. Once connected, the Quake game protocol (documented elsewhere) is used. General notes: Note There are two address forms used. The short form is just a port number. The address that goes along with the port is defined as "whatever address you receive this reponse from". This lets us use the host OS to solve the problem of multiple host addresses (possibly with no routing between them); the host will use the right address when we reply to the inbound connection request. The long from is a full address and port in a string. It is used for returning the address of a server that is not running locally.
