The message id in the CoAP header is used for reliability when transferring a CoAP PDU over a non-reliable transport protocol such as UDP. For message de-duplication, it is useful to have a monotonously increasing number space within a session. Therefore, the context-global value has been moved to coap_session_t. The function coap_new_message_id() now takes a coap_session_t object as its argument.
