Jon Shallow dac6bd3b60 RFC8613: Add in OSCORE support
Based on work done in https://gitlab.informatik.uni-bremen.de/obergman/libcoap

New directories with files
 include/oscore
 src/oscore

New files
 include/coap3/coap_oscore.h
 include/coap3/coap_crypto_internal.h
 include/coap3/coap_oscore_internal.h
 man/coap-oscore-conf.txt.in
 man/coap_oscore.txt.in
 src/coap_oscore.c
 tests/test_oscore.c
 tests/test_oscore.h

Supported by new option (enabled by default)
 ./configure --enable-oscore
 cmake .. -DENABLE_OSCORE=ON

Requires a TLS library configured to do the OSCORE encryption and hashing.
