1247Register a callback for execution when the client sends an (asynchronous)
1248exticmd packet. Exti commands are processed by the server as soon as they
1249are received, i.e. out of order w.r.t. other commands. The first argument
1250is a client socket. Exti commands can be received anytime, even before
1251log-in.
1252
1253If the callback returns something, it is sent back as if reply was being
1254called.
