The Erbium CoAP currently implements draft 08.
Central features are commented in rest-server-example.c.
In general, apps/er-coap-07 supports:
* All CoAP-07 header options
* All draft 08 header options
* CON Retransmissions (note COAP_MAX_OPEN_TRANSACTIONS)
* Blockwise Transfers (note REST_MAX_CHUNK_SIZE)
* Separate Responses (see rest_set_pre_handler() and coap_separate_handler())

The default port for coap-07 is 5683.
* WITH_COAP=3 uses Erbium CoAP 03 apps/er-coap-03/.
The default port for coap-03 is 61616.
er-coap-03 produces some warnings, as it not fully maintained anymore.
* WITH_COAP=0 is a stub to link an Erbium HTTP engine that uses the same resource abstraction (REST.x() functions and RESOURCE macros.
