c9516fbf13 Document exercise_key and fix one incorrect usage
In one place, exercise_key was used in a such a way that if the test
failed inside exercise_key, the test suite would correctly report the
test as failed but would not report the exact location of the failure.
Fix this.

Add documentation for exercise_key that explains how to use it.

e84d5d2f1c psa_copy_key: Add test cases to specifically check non-exportability
Test that copying a non-exportable key doesn't make it exportable.
This complements similar tests that exercise a different usage flag.

6b156df1ba Don't consider RIPEMD160 a PSA_ALG_ANY_HASH candidate
Some parts of the library don't support it, such as RSA PKCS#1v1.5
signature.

8c1247fec9 Add psa_copy_key tests with policy constraints
Test a few cases. The logic to combine the constraint is similar to
the logic to combine the source and target, so it's ok to have less
parameter domain coverage for constraints.

57ab721d8a Test psa_copy_key
Split the testing into tests that exercise policies in
test_suite_psa_crypto and tests that exercise slot content (slot
states, key material) in test_suite_psa_crypto_slot_management.

Test various cases of source and target policies with and without
wildcards. Missing: testing of the policy constraint on psa_copy_key
itself.

Test several key types (raw data, AES, RSA). Test with the
source or target being persistent.

Add failure tests (incompatible policies, source slot empty, target
slot occupied).

ccdce90adb psa: Simplify EC public key format
Remove front matter from our EC key format, to make it just the contents
of an ECPoint as defined by SEC1 section 2.3.3.

As a consequence of the simplification, remove the restriction on not
being able to use an ECDH key with ECDSA. There is no longer any OID
specified when importing a key, so we can't reject importing of an ECDH
key for the purpose of ECDSA based on the OID.

d40c1fbd50 Don't require a type and size when creating a key slot
Remove the type and bits arguments to psa_allocate_key() and
psa_create_key(). They can be useful if the implementation wants to
know exactly how much space to allocate for the slot, but many
implementations (including ours) don't care, and it's possible to work
around their lack by deferring size-dependent actions to the time when
the key material is created. They are a burden to applications and
make the API more complex, and the benefits aren't worth it.

Change the API and adapt the implementation, the units test and the
sample code accordingly.

30f77cdfc1 Add a hash wildcard value for hash-and-sign algorithm
You can use PSA_ALG_ANY_HASH to build the algorithm value for a
hash-and-sign algorithm in a policy. Then the policy allows usage with
this hash-and-sign family with any hash.

Test that PSA_ALG_ANY_HASH-based policies allow a specific hash, but
not a different hash-and-sign family. Test that PSA_ALG_ANY_HASH is
not valid for operations, only in policies.

f055ad7512 Add a safety check to ARRAY_LENGTH
Cause a compilation error on ARRAY_LENGTH(p) where p is a pointer as

c5487a8892 Drop support for psa_key_slot_t in psa_crypto.c
This commit finishes the removal of support for direct access to key
slots in psa_crypto.c.

This marks the end of the necessary phase of the transition to key
handles. The code should subsequently be refactored to move key slot
management from psa_crypto.c to psa_crypto_slot_management.c.

7bc9f68232 Convert the PSA crypto persistent storage tests to the new handle API
Switch from the direct use of slot numbers to handles allocated by
psa_allocate_key.

The general principle for each function is:
* Change `psa_key_slot_t slot` to `psa_key_handle_t handle` or
  `psa_key_id_t key_id` depending on whether it's used as a handle to
  an open slot or as a persistent name for a key.
* Call psa_create_key() before using a slot, instead of calling
  psa_set_key_lifetime to make a slot persistent.

Remove the unit test persistent_key_is_configurable which is no longer
relevant.
