a4668a6b6c Rework TestGenerator to add file targets
BaseTarget-derived targets are now added to TestGenerator.targets in
initialization. This reduces repeated code in generate_xxx_tests.py

61548d1035 Only exercise Brainpool curve keys on one algorithm
There's nothing wrong with ECC keys on Brainpool curves,
but operations with them are very slow. So we only exercise them
with a single algorithm, not with all possible hashes. We do
exercise other curves with all algorithms so test coverage is
perfectly adequate like this.

4bd90dc6b1 Don't exercise OAEP with small key and large hash
RSA-OAEP requires the key to be larger than a function of the hash size.
Ideally such combinations would be detected as a key/algorithm
incompatibility. However key/algorithm compatibility is currently tested
between the key type and the algorithm without considering the key size, and
this is inconvenient to change. So as a workaround, dispense
OAEP-with-too-small-hash from exercising, without including it in the
automatic operation-failure test generation.

e6b85b4d42 Storage format tests: exercise operations with keys
In key read tests, add usage flags that are suitable for the key type and
algorithm. This way, the call to exercise_key() in the test not only checks
that exporting the key is possible, but also that operations on the key are
possible.

This triggers a number of failures in edge cases where the generator
generates combinations that are not valid, which will be fixed in subsequent
commits.

cba28a7d40 Systematically generate test cases for operation setup failure
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
commits.

c7e1ea074a New test suite for systematically generated operation failure tests
The new test suite psa_crypto_op_fail is intended for systematically
generated test cases that ensure that cryptographic operations with
invalid parameters fail as expected. I intend invalid parameters to
cover things like an invalid algorithm, an algorithm that is
incompatible with the operation, a key type that is incompatible with
the algorithm, etc.

This commit just creates the infrastructure. Subsequent commits will
add data generation and test code.

9216536415 Add storage format checks to the interface checker
Expand abi_check.py to look for backward incompatibilities not only in
the interface exposed to application code (and to some extent driver
code), but also to the interface exposed via the storage format, which
is relevant when upgrading Mbed TLS on a device with a PSA keystore.

Strictly speaking, the storage format checks look for regressions in
the automatically generated storage format test data. Incompatible
changes that are not covered by the generated tests will also not be
covered by the interface checker.

A known defect in this commit is that the --brief output is not brief
for storage format checks.

e12e7f47de Get generated data file list from script
Use the generate_psa_tests.py script to generate the list
of test data files used as output files by cmake.

Do this by introducing a new option --list-for-cmake
that prints a semicolon-separated list of the data files
with no terminating newline (since this is how a cmake list
is represented).

Replace the hard-coded output file list with a variable
generated by the script using this option.

Restore the optimization done in
 HEAD^{/Speed up the generation of storage format test cases}
which was lost during refactoring made when adding support for
implicit usage flags.

There are still more than one call to the C compiler, but the extra
calls are only for some key usage test cases.

This is an internal refactoring. This commit does not change the
output of generate_psa_tests.py
