For multipart encrpytion, call psa_cipher_finish(). This is not actually
necessary for non-pathological implementations of ECB (the only currently
supported IV-less cipher algorithm) because it requires the input to be a
whole number of blocks and non-pathological implementations emit the output
block from update() as soon as an input block is available. But in principle
a driver could delay output and thus require a call to finish().

rather than using the value returned by the library. This is equivalent

The test suite test_suite_psa_crypto_op_fail now runs a large number
of automatically generated test cases which attempt to perform a
one-shot operation or to set up a multi-part operation with invalid
parameters. The following cases are fully covered (based on the
enumeration of valid algorithms and key types):
* An algorithm is not supported.
* The key type is not compatible with the algorithm (for operations
that use a key).
* The algorithm is not compatible for the operation.
Some test functions allow the library to return PSA_ERROR_NOT_SUPPORTED
where the test code generator expects PSA_ERROR_INVALID_ARGUMENT or vice
versa. This may be refined in the future.
Some corner cases with algorithms combining a key agreement with a key
derivation are not handled properly. This will be fixed in follow-up

At least twice, we added a classification flag but forgot to test it in the
relevant test functions. Add some protection so that this doesn't happen
again. In each classification category, put a macro xxx_FLAG_MASK_PLUS_ONE
at the end. In the corresponding test function, keep track of the flags that
are tested, and check that their mask is xxx_FLAG_MASK_PLUS_ONE - 1 which is
all the bits of the previous flags set.
Now, if we add a flag without testing it, the test
TEST_EQUAL( classification_flags_tested, xxx_FLAG_MASK_PLUS_ONE - 1 )
will fail. It will also fail if we make the set of flag numbers
non-consecutive, which is ok.
This reveals that three algorithm flags had been added but not tested (in
two separate occasions). Also, one key type flag that is no longer used by
the library was still defined but not tested, which is not a test gap but is
inconsistent. It's for DSA, which is relevant to the PSA encoding even if
Mbed TLS doesn't implement it, so keep the flag and do test it.

The status of signature wildcards with respect to PSA_ALG_IS_HASH_AND_SIGN
is unclear in the specification. A wildcard is usually instantiated with a
specific hash, making the implementation hash-and-sign, but it could also be
instantiated with a non-hash-and-sign algorithm. For the time being, go with
what's currently implemented, which is that they are considered
hash-and-sign.

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.

use PSA_HASH_BLOCK_LENGTH for at the moment.

This is part of the definition of the encoding, not a choice of test
parameter, so keep it with the test code.

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.
