When generated by exp_mod, RR has enough limbs to be passed as a
parameter to core functions. If it is received from the caller, it might
be of any length.

Assigning the return value of a function that returns a struct with a
flexible array member does not fill the flexible array member, which leaves
a gap in the initialization that could be surprising to programmers. Also,
this is a borderline case in ABI design which could cause interoperability
problems. So remove this function.
This gets rid of an annoying note from GCC about ABI compatibility on
(at least) x86_64.

Return MBEDTLS_ERR_PEM_PASSWORD_MISMATCH instead of
MBEDTLS_ERR_PEM_BAD_INPUT_DATA in case of errors.

Document and test the current behavior, even if it is weird:
* For Weierstrass keys, the error is MBEDTLS_ERR_MPI_BUFFER_TOO_SMALL,
not MBEDTLS_ERR_ECP_BUFFER_TOO_SMALL.
* For Weierstrass keys, a smaller output buffer is ok if the output fits.

Now that we have padding verification after decryption and since
this can be used to validate the password as well there is no
need to parse ASN1 content any more, so we can simplify/remove
that dependency.

We were testing the internal consistency of the resulting key, and that the
resulting key had the right metadata, but we were not testing that the PSA
key had the expected key material. Comparing the public keys fixes that.

Test that a PK key and a PSA key are consistent, i.e. that they have the
same type (or are a key pair and the corresponding public key) and that
they have the same public key.

In TLS 1.3 early data tests, to reduce the risk
of not updating a switch over possible scenarios
when adding a new scenario, add systematically a
default case that fails the test.

This was only tested with opaque keys. Since the code paths are different
depending on the PK type, we also need to test RSA and ECKEY.

Custom-e RSA key generation is not yet supported in the test driver, and we
don't support fallback from the test driver to the built-in
implementation (even though we're testing with MBEDTLS_RSA_C). So for the
time being, only run psa_generate_key_ext test cases for RSA with a custom
public exponent when using the built-in implementation.
Add a test case to validate that psa_generate_key_ext test cases for RSA
with a custom public exponent returns NOT_SUPPORTED (rather than silently
doing the wrong thing) when not using built-in RSA (which is subtly
different from when having accelerated RSA: if both are enabled, which we
currently don't do in all.sh, then this should be supported and this is
validated by the test cases above).
This wart will be resolved when we add support for drivers with a
generate_key_ext entry point.

Instead of passing the size of the whole structure, just pass the data
length and let the implementation worry about adding the size of the
structure. The intent with passing the structure size was to allow
the client code in a client-server implementation to know nothing
about the structure and just copy the bytes to the server. But that was not
really a useful consideration since the application has to know the
structure layout, so it has to be available in the client implementation's
headers. Passing the method data length makes life simpler for everyone by
not having to worry about possible padding at the end of the structure, and
removes a potential error condition
(method_length < sizeof(psa_key_generation_method_t)).

In valid_parameters_pkwrite, we first parse a public key then test
with mbedtls_pk_write_xxx functions. So valid_parameters_pkwrite
should depend on both MBEDTLS_PK_WRITE_C and MBEDTLS_PK_PARSE_C.

Calling mbedtls_test_fail() attempts to lock the test data mutex.
Unfortunately we were calling this from places where we already held
this mutex, and this mutex is not recursive, so this deadlocks. Split
out mbedtls_test_fail() into mbedtls_test_fail_internal() in order to
address this.

This fixes the ability to exercise keys in configurations where MD5 is
supported for direct use, but not inside some accelerated algorithms. This
is the case in `all.sh test_psa_crypto_config_accel_ecc_ecp_light_only` and
some other accelerated-ECC components of `all.sh`, where the driver is built
without MD5 support but built-in MD5 remains enabled.
This is only a hack, not a theoretically correct fix, but a correct fix is
out of scope of my current work.

Parsing a key and importing it into PSA may result in a policy that
specifies an algorithm that is not included in the build. This happens if
the key type is supported, but not the algorithm, e.g. in a build with
MBEDTLS_ECP_C but not MBEDTLS_ECDSA_C.
