  • gcc warnings after upgrading mosquitto to 2.1.2

    ```
    In file included from mqtt.h:36,
    from logfile.h:26,
    from sbbs.h:298,
    from js_conio.cpp:26:
    /usr/include/mqtt_protocol.h:2:2: warning: #warning "Please replace '#include <mqtt_protocol.h> with #include <mosquitto.h>" [-Wcpp]
    2 | #warning "Please replace '#include <mqtt_protocol.h> with #include <mosquitto.h>"
    | ^~~~~~~
    ```

    Seems to occur anywhere mqtt_protocol.h is called.

    Not sure why it took me 4 months to actually dig into this a tiny bit to actually see and try to understand this - and I imagine it's probably already known by the devs, but I noticed /usr/include/mqtt_protocol.h contains:

    ```
    #include <mosquitto/mqtt_protocol.h>
    #warning "Please replace '#include <mqtt_protocol.h> with #include <mosquitto.h>"
    ```

    /usr/include/mosquitto/mqtt_protocol.h contains everything needed, and then /usr/include/mosquitto.h includes /usr/include/mosquitto/mqtt_protocol.h.

    So, is this just a warning that has come up in the latest version of mqtt (ie, not much to do with Synchronet except that Synchronet is still probably using /usr/include/mqtt_protocol.h at this point) all because mqtt_protocol.h is being moved to a new location?

    I suppose this would lead me to believe this issue has been left open as a reminder that once mqtt is updated in more "stable" distros that this change should be made?

    If so, kudos to upstream for giving plenty of fair warning (pun intended)!
