Renamed hmac_ctx to opad and removed null check.
...
this array is now part of the struct and not dynamically allocated
so it can't be null.

Add static internal MAC finish function
...
add new psa_mac_finish_internal() to be called by psa_mac_finish() and
psa_mac_verify() in order to be able to check key usage separatly.

Avoid empty unions
...
When no algorithms are present in a category (e.g. no AEAD algorithm),
the union in the corresponding operation structure was empty, which is
not valid C. Add a dummy field to avoid this.

Implement hash functions
...
New header file crypto_struct.h. The main file crypto.sh declares
structures which are implementation-defined. These structures must be
defined in crypto_struct.h, which is included at the end so that the
structures can use types defined in crypto.h.
Implement psa_hash_start, psa_hash_update and psa_hash_final. This
should work for all hash algorithms supported by Mbed TLS, but has
only been smoke-tested for SHA-256, and only in the nominal case.
