This is a rework of the crypto adaptor layer for HMAC to be similar to that for hashes. This facilitates the use of incremental HMAC'ing of the protected headers in place so there is no need for a fixed buffer for them and so their size limit is removed.
This also resulted in a code size and complexity reduction, particularly because both Mac compute and validate use exactly the same utility functions and crypto layer.
