1052Register a callback for execution when the client sends an (asynchronous)
1053exticmd packet. Exti commands are processed by the server as soon as they
1054are received, i.e. out of order w.r.t. other commands. The first argument
1055is a client socket. Exti commands can be received anytime, even before
1056log-in.
