Secure wolfMQTT SN with wolfSSL DTLS

The sensor network sub-specification of MQTT does not designate a method for securing the communication between the clients and the gateway. We here at wolfSSL think that is unacceptable! Using the DTLS library of wolfSSL, we would like to protect the sensor data all the way from the client to the gateway, and then from the gateway on to the broker using standard TLS (also from wolfSSL).
