Gilles Peskine 35115f9c1a New algorithm PSA_ALG_RSA_PSS_ANY_SALT
This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.

In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).

Changes in this commit:

* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
  PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
  PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
  generate_psa_constant_names).

Add test case generation for usage extensions when loading keys
Add test cases validating that if a stored key only had the hash policy,
then after loading it psa_get_key_attributes reports that it also has the
message policy, and the key can be used with message functions.

Gilles Peskine 08966e6fbc Remove duplicates from enumerated test inputs
When generating expressions to construct test case data, there can be
duplicate values, for example if a value of the form C(A) is present
as such in test_suite_psa_crypto_metadata.data and also constructed by
enumerating the argument A for the constructor C. Eliminate such
duplicates in generate_expressions.

This commit removes many test cases that were exact duplicates (and
were near-duplicates differing only in whitespace before the
whitespace normalization).

Gilles Peskine b93f854f4c Expand psa_generate_tests to support constructor arguments
In macro_collector.py, base InputsForTest on PSAMacroEnumerator rather
than PSAMacroCollector. It didn't make much sense to use
PSAMacroCollector anymore since InputsForTest didn't use anything
other than the constructor.

psa_generate_tests now generates arguments for more macros.
In particular, it now collects macro arguments from
test_suite_psa_crypto_metadata. Algorithms with parameters are now
supported.

Gilles Peskine d6d2d6a7d7 Use InputsForTest in generate_psa_tests
In generate_psa_tests, use InputsForTest rather than PSAMacroCollector
to gather values. This way, the enumeration of values to test includes
values used in metadata tests in addition to constructors parsed from
header files. This allows greater coverage of values built from
constructors with arguments. This doesn't make a difference yet, but
it will once algorithm constructors with arguments are supported in
generate_psa_tests.

Make the injection of numerical values optional. They are useful for
test_psa_constant_names, so keep them there. Don't use them for
not-supported tests: they might make sense, but the current code
wouldn't work since it doesn't know how to make up fake key material
or what dependencies to generate. Don't use them for storage tests:
they only make sense for supported values.

Don't inject 'PSA_SUCCESS': that's superfluous.

Gilles Peskine 33c601cb73 Hook up PSAMacroCollector to PSAMacroEnumerator
Make it possible to enumerate the key types, algorithms, etc.
collected by PSAMacroCollector.

This commit ensures that all fields of PSAMacroEnumerator are filled
by code inspection. Testing of the result may reveal more work to be
done in later commits.

At the moment it makes no difference, but it could if e.g. a new

Gilles Peskine 13d60eb4fc MacroCollector: default to not including intermediate macros
By default, exclude macros whose numerical value is not a valid member
of the semantic type (e.g. PSA_ALG_xxx_BASE is not itself an
algorithm, only an intermediate value used to construct others). But
do include them with include_intermediate=True, which
generate_psa_constants.py does.
