1248Register a callback for execution when the client sends an (asynchronous)
1249exticmd packet. Exti commands are processed by the server as soon as they
1250are received, i.e. out of order w.r.t. other commands. The first argument
1251is a client socket. Exti commands can be received anytime, even before
1252log-in.
1253
1254If the callback returns something, it is sent back as if reply was being
1255called.
