d7b3d92476 Change sha256 output type from an array to a pointer
The output parameter of mbedtls_sha256_finish_ret and mbedtls_sha256_ret
now has a pointer type rather than array type. This removes spurious
warnings in some compilers when outputting a SHA-224 hash into a
28-byte buffer.

233f91d5c1 Add bits output to validate_key and import_key
When importing a key, the code that parses the input needs to
determine the key size ("bits" attribute). This is specific to import
since other key creation methods require the caller to supply a size.
Therefore, add an extra output parameter `bits` to the "import_key"
entry point for opaque drivers. Likewise, add a `bits` output
parameter to the "validate_key" entry point for transparent drivers.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID
. psa_key_file_id_make to mbedtls_svc_key_id_make

b51f96a7bf Pure C configuration of PSA crypto mechanisms
Proposed specification for conditional inclusion of cryptographic
mechanism through the PSA API in Mbed TLS.

The inclusion of a mechanism is based on a declaration of boolean
symbols by the application. There is a symbol for each key type or
parametrized key type constructor, and for each algorithm or
parametrized algorithm constructor.

This is work in progress, presented for a first design discussion.

d89cd742eb Specify that transparent drivers are considered in order
There is little point in leaving the order in which drivers are
considered unspecified. This gives flexibility to the implementation
for a process that is generally performed at build time, not in a
constrained environment. Having a well-defined order is especially
useful with fallback.

91cbf56d4c Specify what happens if multiple capabilities apply
It's ok if they map to the same function names and an error otherwise.

It's an error to have multiple opaque drivers for the same location.

If multiple transparent drivers apply, which one applies is unspecified.

c7cf13356c Define the semantics of capabilities
The existing description of the syntax of capabilities also describes
the semantics of each property, but the semantics of the capability as
a whole is not immediately clear. Add a subsection that explains
precisely when a capability is applicable.

1bc9c4c8c8 Make entry points mandatory in capabilities
Inferring entry points from algorithms is nice in that it makes
capability specifications shorter and less redundant, but that's not
really important. It also makes capabilities more fragile: if the core
starts supporting new mechanisms based on the same algorithm (for
example, adding hash-and-sign when only sign-the-hash existed before),
a driver only supporting the old mechanisms would fail at build time.
So make entry points mandatory.

This has the benefit of making the semantics of capabilities easier to
describe.

there's no reason to deviate from the naming convention.
