    Add a public "no value" function

    This can be used to clear a 'retained' topic (of any type).

    Track broker-connected status via Mosquitto connect/disconnect callbacks

    I think this might fix issue #781. I suspect that SBBS (the MQTT client) is being disconnected by the server ("due to protocol error") *after* the
    call to mosquitto_connect_bind() is successful. We don't have any correponding log output for this case, but at least we can track the connection status accurately using the Mosquitto client callbacks and not try to publish when we're not connected.

    Don't publish to the initial server topics (e.g. version) until after connect

    Fix for issue #884

    We must wait until the connect_callback() has been called to publish these messages. Using mqtt.server_version as the indicator of an initial startup connection versus a re-connection (due to broker-connection loss), i.e.
    setting to NULL after initial connection.
