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.

8c9def3e7f PSA: Implement MAC functions

308b91d7db Wrote documentation for several functions, macros and types 
Document key import/export functions, hash functions, and asymmetric
sign/verify, as well as some related macros and types.

Nicer formatting for return values: use \retval.

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.

a590529938 Greatly expanded mbedtls_to_psa_error

DHM, everything ECC, HMAC_DRBG).

98f0a24255 Improve key type and algorithm encodings

make more sense.

20035e3579 PSA crypto: asymmetric signature (RSA PKCS#1v1.5 only) 
Define hash algorithms and RSA signature algorithms.

New function psa_asymmetric_sign.

Implement psa_asymmetric_sign for RSA PKCS#1 v1.5.

969ac726d9 PSA RSA key import: don't rely on pk so much 
Don't use the pk module except as required for pkparse/pkwrite. The
PSA crypto layer is meant to work alongside pk, not on top of it.

Fix the compile-time dependencies on RSA/ECP handling in
psa_export_key, psa_destroy_key and psa_get_key_information.

2f9c4dc5ad Add key management functions 
Define psa_key_type_t and a first stab at a few values.

New functions psa_import_key, psa_export_key, psa_destroy_key,
psa_get_key_information. Implement them for raw data and RSA.

Under the hood, create an in-memory, fixed-size keystore with room
for MBEDTLS_PSA_KEY_SLOT_COUNT - 1 keys.

1d26709dbd New function mbedtls_rsa_get_bitlen 
Add a new function mbedtls_rsa_get_bitlen which returns the RSA key
size, i.e. the bit size of the modulus. In the pk module, call
mbedtls_rsa_get_bitlen instead of mbedtls_rsa_get_len, which gave the
wrong result for key sizes that are not a multiple of 8.

This commit adds one non-regression test in the pk suite. More tests
are needed for RSA key sizes that are a multiple of 8.

This commit does not address RSA alternative implementations, which
only provide an interface that return the modulus size in bytes.

e59236fc17 Add PSA crypto module 
New module psa_crypto.c (MBEDTLS_PSA_CRYPTO_C):
Platform Security Architecture compatibility layer on top of
libmedcrypto.

Implement psa_crypto_init function which sets up a RNG.

Add a mbedtls_psa_crypto_free function which deinitializes the
library.

Define a first batch of error codes.
