Group together and document the run-time checks available for checking the libcoap built-in functionality based on the ./cconfigure and / or CMakeLists.txt options. Create include/coap3/coap_defines.h file that contains a list of COAP_ #defines created from the options defined when running ./configure or cmake. Add additional coap_*_is_supported() functions.
