3fa684ed91 Allow importing Montgomery public keys in PSA Crypto
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.

d3beca9e38 Test Everest with only Curve25519 enabled
tests/scripts/curves.pl tests the library with a single curve enabled.
This uses the legacy ECDH context and the default ECDH implementation.
For Curve25519, there is an alternative implementation, which is
Everest. Test this. This also tests the new ECDH context, which
Everest requires.

a2611604d4 curves.pl: test with each elliptic curve enabled
Previously curves.pl tested with all elliptic curves enabled except
one, for each curve. This catches tests that are missing dependencies
on one of the curve that they use, but does not catch misplaced
conditional directives around parts of the library.

Now, we additionally test with a single curve, for each curve. This
catches missing or extraneous guards around code that is specific to
one particular curve or to a class of curves.

de8593f2fe Implement and test mbedtls_ecp_write_key
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.

0d7216511f Fix erroneous skip of test cases for disabled ciphersuites
Test cases that force a specific ciphersuites are only executed if
this ciphersuite is enabled. But there are test cases (for RC4) whose
goal is to check that the ciphersuite is not used. These test cases
must run even if (or only if) the ciphersuite is disable, so add an
exception for these test cases.

b20b873bff Remove metadata tests for features that are not implemented
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)

In test functions calling mbedtls_test_unhexify(), change the

That way the `unhexify` operation is done by the test
framework and not by the unit test code.

local variable that use to store the `unhexify` version of
the `char*` parameter.
