d586b82e12 exercise_key: signature: detect function/algorithm incompatibility
Don't try to use {sign,verify}_message on algorithms that only support
{sign_verify}_hash. Normally exercise_key() tries all usage that is
supported by policy, however PSA_KEY_USAGE_{SIGN,VERIFY}_MESSAGE is implied
by PSA_KEY_USAGE_{SIGN,VERIFY}_HASH so it's impossible for the test data to
omit the _MESSAGE policies with hash-only algorithms.

7acb1980ee Use PSA_AEAD_NONCE_LENGTH when exercising AEAD keys
Don't re-code the logic to determine a valid nonce length.

This fixes exercise_key() for PSA_ALG_CHACHA20_POLY1305, which was trying to
use a 16-byte nonce.

4c0ec7651b tests: psa: Refine choice of default hash algorithm for signature
As PSA signatures rely on built-in hash implementations
(cannot take an advantage of an accelerator for the
time being), chose an available built-in hash for
tests exercising a signature key.

f7b4137e69 Untangle PSA_ALG_IS_HASH_AND_SIGN and PSA_ALG_IS_SIGN_HASH
The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).

In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.

Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.
```
git grep -l IS_HASH_AND_SIGN ':!include/psa/crypto_values.h' | xargs perl -i -pe 's/ALG_IS_HASH_AND_SIGN/ALG_IS_SIGN_HASH/g'

89615eefe7 Show values when TEST_EQUAL fails
When TEST_EQUAL fails, show the two numerical values in the test log (only
with host_test). The values are printed in hexa and signed decimal.

The arguments of TEST_EQUAL must now be integers, not pointers or floats.
The current implementation requires them to fit in unsigned long long
Signed values no larger than long long will work too. The implementation
uses unsigned long long rather than uintmax_t to reduce portability
concerns. The snprintf function must support "%llx" and "%lld".

For this purpose, add room for two lines of text to the mbedtls_test_info
structure. This adds 154 bytes of global data.

2385f71abd Fix and simplify test assertions
mbedtls_test_fail does not copy the failure explanation string, so
passing a string on the stack doesn't work. This fixes a garbage
message that would appear if a test triggered a non-implemented code
path.

More generally, just use TEST_ASSERT instead of explicitly calling
mbedtls_test_fail, since we aren't playing any tricks with the error
location.

cc9db30851 exported_key_sanity_check: make checks slightly more systematic
Shuffle the logic in mbedtls_test_psa_exported_key_sanity_check()
somewhat. The resulting behavior changes are:

* Always check the exported length against PSA_EXPORT_KEY_OUTPUT_SIZE,
  even for unstructured key types.
* Always complain if a key type is not explicitly covered, not just
  for public keys.
