The client opens a connection to the primary game server port and sends the
`INIT_JS5REMOTE_CONNECTION` packet, which consists of a single byte opcode
(`15`) followed by the client's build number as an integer.
The server responds with a single `0` byte if the connection attempt is
successful. It may also respond with `CLIENT_OUT_OF_DATE` (`6`), `SERVER_FULL`
(`7`) or `IP_LIMIT` (`9`), after which the connection will be closed.
After a successful connection attempt, the connection remains in JS5 mode for
the rest of its life.
JS5 is a request/response protocol with support for pipelining - the 550 client
is capable of handling up to 20 prefetch and 20 urgent in-flight requests.
