    [1986] Fix unit tests for extra messages

    [1986] Messaging between auth and DDNS
    
    cleanup and logging pending, but basic functionality is there;
    upon start, b10-ddns will send auth a command to start forwarding
    upon shutdown, b10-ddns will send auth a command to stop forwarding
    auth also sends b10-ddns a command to send the above command, so that a restart of auth does not make things break down (auth does not expect an answer here, it is only a hint; b10-ddns, if running, will then send its start command to auth again)
