e9b55929dc Remove useless platform macro redefinitions: automatic part
Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.

This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')
```

130fa4d376 Rm local helper now that a global one is available
There is a small difference: the global function only works for hashes
that are included in the build, while the old one worked for all hashes
regardless of whether they were enabled or not.

We'll see in the CI is this causes any issues.

4772884133 New internal module for managing hash information
Using static inline functions is bad for code size; the function from
md_internal.h was already used from 3 different C files, so already was
copied at least 3 times in the library, and this would only get worse
over time.

Use actual functions, and also share the actual data between them.

Provide a consistent set of operations. Conversion to/from
human-readable string was omitted for now but could be added later if
needed.

In the future, this can be used to replace other similar (inline)
functions that are currently scattered, including (but perhaps not
limited to):
- mbedtls_psa_translate_md() from psa_util.h
- mbedtls_md_info_from_psa() (indirectly) from psa_crypto_hash.h
- get_md_alg_from_psa() from psa_crypto_rsa.c

3f4778995e Rm dependency on MD in psa_crypto_rsa.c

md.c, but there was still a dependency in the corresponding part in PSA.

40170d9516 tests: Rename test driver entry points
Rename test driver entry points to
libtestdriver1_<name of the Mbed TLS entry point>.

This aligns with the renaming of all Mbed TLS APIs
for the test driver library (that will be put in place
in the following commits) to avoid name conflicts
when linking it with the Mbed TLS library.

is used. Their purpose is only to test the PSA configuration
thus there is no good reason to use them out of this scope.

Add test driver support for opaque key import
-Add test driver support to import/export while wrapping keys
 meant to be stored in the PSA core as opaque( emulating an
 SE without storage ).
-Export validate_unstructured_key_bit_size as
 psa_validate_unstructured_key_bit_size, thereby changing its scope.
-Improve the import/export test cases in test_suite_psa_crypto to also
 cover opaque keys, thereby avoiding duplication.

0af093b6c8 PSA RSA PSS: pass pre-hash algorithm to Mbed TLS
PSA Crypto always passed MBEDTLS_MD_NONE to Mbed TLS, which worked well
as Mbed TLS does not use this parameter for anything beyond determining
the input lengths.

Some alternative implementations however check the consistency of the
algorithm used for pre-hash and for other uses in verification (verify
operation and mask generation) and fail if they don't match. This makes
all such verifications fail.

Furthermore, the PSA Crypto API mandates that the pre-hash and internal
uses are aligned as well.

Fixes #3990.

84dea01f36 Add RNG params to private key parsing
This is necessary for the case where the public part of an EC keypair
needs to be computed from the private part - either because it was not
included (it's an optional component) or because it was compressed (a
format we can't parse).

This changes the API of two public functions: mbedtls_pk_parse_key() and
mbedtls_pk_parse_keyfile().

Tests and programs have been adapted. Some programs use a non-secure RNG
(from the test library) just to get things to compile and run; in a
future commit this should be improved in order to demonstrate best
practice.

424fa93efd psa: Support RSA signature without MBEDTLS_GENPRIME
On space-constrained platforms, it is a useful configuration to be able
to import/export and perform RSA key pair operations, but to exclude RSA
key generation, potentially saving flash space. It is not possible to
express this with the PSA_WANT_ configuration system at the present
time. However, in previous versions of Mbed TLS (v2.24.0 and earlier) it
was possible to configure a software PSA implementation which was
capable of making RSA signatures but not capable of generating RSA keys.
To do this, one unset MBEDTLS_GENPRIME.

Since the addition of MBEDTLS_PSA_BUILTIN_KEY_TYPE_RSA_KEY_PAIR, this
expressivity was lost. Expressing that you wanted to work with RSA key
pairs forced you to include the ability to generate key pairs as well.

Change psa_crypto_rsa.c to only call mbedtls_rsa_gen_key() if
MBEDTLS_GENPRIME is also set. This restores the configuration behavior
present in Mbed TLS v2.24.0 and earlier versions.

It left as a future exercise to add the ability to PSA to be able to
express a desire for a software or accelerator configuration that
includes RSA key pair operations, like signature, but excludes key pair
generation.

Without this change, linker errors will occur when attempts to call,
which doesn't exist when MBEDTLS_GENPRIME is unset.
    psa_crypto_rsa.c.obj: in function `rsa_generate_key':
    psa_crypto_rsa.c:320: undefined reference to `mbedtls_rsa_gen_key'
