1043extcmd packet. Ext commands will be processed in the order they are
1044received by the server, like other user commands. The first argument is

1046has logged in successfully.

1053Register a callback for execution when the client sends an (asynchronous)
1054exticmd packet. Exti commands are processed by the server as soon as they
1055are received, i.e. out of order w.r.t. other commands. The first argument
1056is a client socket. Exti commands can be received anytime, even before
1057log-in.
