Gilles Peskine 9ef733faa0 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.
