0eb6e97ac6 Merge pull request #4 from ARMmbed/psa-wrapper-apis-march-2 
Interfaces: general framework for key types and algorithms; key import, export and destruction; multipart hash, MAC, cipher and AEAD operations; asymmetric sign/verify, key lifetimes and policies.

Implementation: key import, export and destruction (RSA, symmetric keys); multipart hash and MAC operations. Tested only with a few smoke tests.

058e0b9963 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.

d393e18f90 Add psa_set_key_lifetime 
It is likely that most implementations won't support this function.
But in case an implementation wants to provide it, standardize its
interface.

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.
