a81d85b732 Sort out ECDSA mechanisms 
* Distinguish randomized ECDSA from deterministic ECDSA.
* Deterministic ECDSA needs to be parametrized by a hash.
* Randomized ECDSA only uses the hash for the initial hash step,
  but add ECDSA(hash) algorithms anyway so that all the signature
  algorithms encode the initial hashing step.
* Add brief documentation for the ECDSA signature mechanisms.
* Also define DSA signature mechanisms while I'm at it. There were
  already key types for DSA.

526fab0066 Fix parameter name signature_size for psa_asymmetric_verify 
It should have been signature_length, following our conventions.

55bf3d1171 Sort out RSA mechanisms 
* PSS needs to be parametrized by a hash.
* Don't use `_MGF1` in the names of macros for OAEP and PSS. No one
  ever uses anything else.
* Add brief documentation for the RSA signature mechanisms.

7ed29c56f1 Rename PSA_ALG_RSA_GET_HASH to PSA_ALG_SIGN_GET_HASH 
And don't use it for HMAC when there's a perfectly serviceable
PSA_ALG_HMAC_HASH. HMAC isn't hash-and-sign.

7baf0d5702 psa: doxygen: Fix parameters reference 
Doxygen interprets `\param` as starting documentation for a new param, or
to extend a previously started `\param` documentation when the same
reference is used. The intention here was to reference the function
parameter, not extend the previous documentation. Use `\p` to refer to
function parameters.

e9a0a9d74d Update documentation of psa_success_t 
Now that the type is not an enum, explain what values are valid.

Also add a comment to explain the #if defined(PSA_SUCCESS) temporary hack.

c2a7976886 PSA Crypto error code definitions

Conditionally defining PSA_SUCCESS and psa_status_t.

48c0ea14c6 Remove PSA_KEY_TYPE_IS_RAW_BYTES from crypto.h 
It isn't used to define other macros and it doesn't seem that useful
for users. Remove it, we can reintroduce it if needed.

Define a similar function key_type_is_raw_bytes in the implementation
with a clear semantics: it's a key that's represented as a struct
raw_data.

4e69d7a9a7 psa_generate_key: pass parameters_size argument 
When calling psa_generate_key, pass the size of the parameters buffer
explicitly. This makes calls more verbose but less error-prone. This
also has the benefit that in an implementation with separation, the
frontend knows how many bytes to send to the backend without needing
to know about each key type.

e1fed0de18 Define elliptic curve identifiers from TLS 
Instead of rolling our own list of elliptic curve identifiers, use one
from somewhere. Pick TLS because it's the right size (16 bits) and
it's as good as any.

625b01c9c3 Add OAEP placeholders in asymmetric encrypt/decrypt 
Replace PSS placeholders by OAEP placeholders. PSS is a signature
algorithm, not an encryption algorithm.

723feffe15 Fix some errors in PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE 
A call to PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE wouldn't even have
compiled. Fix some obvious errors. This is still untested.
