1203Register a callback for execution when the client sends an (asynchronous)
1204exticmd packet. Exti commands are processed by the server as soon as they
1205are received, i.e. out of order w.r.t. other commands. The first argument
1206is a client socket. Exti commands can be received anytime, even before
1207log-in.
1208
1209If the callback returns something, it is sent back as if reply was being
1210called.
