Return a name that more clearly returns nonzero=true=good, 0=bad. We'd
normally expect check_xxx to return 0=pass, nonzero=fail so
check_parity was a bad name.

An early draft of the PSA crypto specification required multipart
operations to keep working after destroying the key. This is no longer
the case: instead, now, operations are guaranteed to fail. Mbed TLS
does not comply yet, and still allows the operation to keep going.
Stop testing Mbed TLS's non-compliant behavior.

Rely on Asan to detect a potential buffer overflow, instead of doing a
manual check. This makes the code simpler and Asan can detect
underflows as well as overflows.

In the cleanup code for persistent_key_load_key_from_storage(), we
only attempt to reopen the key so that it will be deleted if it exists
at that point. It's intentional that we do nothing if psa_open_key()
fails here.

RFC5280 does not state that the `revocationDate` should be checked.
In addition, when no time source is available (i.e., when MBEDTLS_HAVE_TIME_DATE is not defined), `mbedtls_x509_time_is_past` always returns 0. This results in the CRL not being checked at all.

PSA Crypto was checking the byte length of a to-be-imported public ECP key
against the expected length for Weierstrass keys, forgetting that
Curve25519/Curve448 exists.

They did not match their description, probably due to a botched manual
endianness conversion where the nibbles also got swapped.

mbedtls_ecp_write_key is a mirror function to mbedtls_ecp_read_key, which
writes a private key back into a byte buffer in the correct format.
This is a helpful convenience function, since the byte order is defined
differently between Montgomery and Weierstrass curves. Since this difference
is accounted for in mbedtls_ecp_read_key, it made sense to add
mbedtls_ecp_write_key for the purpose of abstracting this away such that
psa_export_key doesn't need to take byte order into account.

A symbol has been removed from the mbedcrypto library since the last
release:

size_t* bits )
This is an ABI break and we need to increase the SO version.

The metadata tests depend on the corresponding feature because there
is no guarantee that the metadata is correct if the feature is
disabled. There are metadata test cases for some algorithms and key
types that are declared but not supported. These test cases are
present but can never run.
It is debatable whether having these test cases is a good thing in
case they become runnable in the future, or a bad thing because
they're dead code. We're working on detecting test cases that are
never executed for accidental reasons (e.g. typo in a dependency or
missing configuration on the CI), and having test cases that are
deliberately never executed messes this up. So remove these test
cases. If we do implement the corresponding feature, it'll be easy to
add the corresponding metadata test cases.
The features that had metadata tests but no implementations were:
* SHA-512/256 and SHA-512/224 (hypothetical dependency: MBEDTLS_SHA512_256)
* DSA (hypothetical dependency: MBEDTLS_DSA_C)
* SHA-3 and HMAC-SHA-3 (hypothetical dependency: MBEDTLS_SHA3_C)

Rework mbedtls_test_unhexify to extend its scope of usage.
Return in error when the function detects an error instead
of calling mbedtls_exit().
Improve safety by checking the output buffer is not overrun.

In test functions calling mbedtls_test_unhexify(), change the
type of the associated parameters from `char*` to `data_t`.
That way the `unhexify` operation is done by the test
framework and not by the unit test code.
Use for the new parameters of type data_t the name of the
local variable that use to store the `unhexify` version of
the `char*` parameter.

anynore, only *output* variables.
- Use two different buffers to store the expected output
of mbedtls_chacha20_crypt() (expected_output_str[]) and
the ASCII string representation of the output of
mbedtls_chacha20_crypt() (output_string[]). Both were
stored in dst_str[] before.
