7da96b0d91 Reorder parameters of AEAD unit tests to be more logical
Pass the nonce first, then the AD, then the input. This is the order
in which the data is processed and it's the order of the parameters to
the API functions.

c426352ec5 check-files: exclude .git and third-party files
Exclude ".git" directories anywhere. This avoids spurious errors in git
checkouts that contain branch names that look like a file
check-files.py would check.

Exclude "mbed-os" anywhere and "examples" from the root. Switch to the
new mechanism to exclude "yotta/module". These are directories where
we store third-party files that do not need to match our preferences.

Exclude "cov-int" from the root. Fix #1691

e04d4e6d13 Don't try to disable ASLR
We don't need to disable ASLR, so don't try. If gdb tries but fails,
the test runs normally, but all.sh then trips up because it sees
`warning: Error disabling address space randomization: Operation not permitted`
and interprets it as an error that indicates a test failure.

bd7dea9e64 Use ASSERT_COMPARE instead of memcmp in PSA tests
This commit fixes some missing size comparison. In
aead_encrypt_decrypt, aead_encrypt and aead_decrypt, the test code
would not have noticed if the library function had reported an output
length that was not the expected length.

3c22596d9b New macro ASSERT_COMPARE to compare two buffers
ASSERT_COMPARE tests that the two buffers have the same size and
content. The intended use is to replace TEST_ASSERT( size1 == size2 )
followed by memcmp on the content. Keep using memcmp when comparing
two buffers that have the same size by construction.

8cebbba7e6 Use ASSERT_ALLOC instead of mbedtls_calloc in PSA tests
This commit resolves a bug whereby some test cases failed on systems
where mbedtls_calloc returns NULL when the size of 0, because the test
case asserted `pointer != NULL` regardless of the size.

b75125c5ff New macro ASSERT_ALLOC to allocate memory in tests
The new macro ASSERT_ALLOC allocates memory with mbedtls_calloc and
fails the test if the allocation fails. It outputs a null pointer if
the requested size is 0. It is meant to replace existing calls to
mbedtls_calloc.

d9c8260f23 Add dependencies to metadata validation tests
If some algorithms are excluded in the build, it's ok for the corresponding
macros not to give the correct results. Therefore the corresponding test cases
should depend on the implementation of the algorithm. For example, it's ok for
PSA_HASH_MAX_SIZE to be less than PSA_HASH_SIZE(PSA_ALG_SHA_512) if we build
without SHA-512 support, and we indeed do this. It's even ok for an
implementation to return 0 for PSA_ALG_IS_HASH(PSA_ALG_SHA_512) if it doesn't
support SHA-512; we return 1 anyway but the tests are less
implementation-specific if we don't enforce it.

This commit adds dependencies on symbols that don't exist in Mbed TLS,
for algorithms that Mbed TLS doesn't implement. These are:
MBEDTLS_SHA512_256 for SHA-512/256, MBEDTLS_SHA3_C for SHA-3,
MBEDTLS_DSA_C and MBEDTLS_DSA_DETERMINISTIC for DSA, and
MBEDTLS_ECP_DP_xxx_ENABLED for elliptic curves that have a PSA
encoding but are not supported in Mbed TLS.

49cd329908 Key type validation tests
For all key types, validate feature test macros (PSA_KEY_TYPE_IS_xxx).

For asymmetric keys (public key or key pair), validate the
corresponding public/pair type.

For ECC keys, validate GET_CURVE.

17351eb7f2 Algorithm validation tests
For all algorithms, validate feature test macros (PSA_ALG_IS_xxx).

For hash algorithms, validate the exact hash size, and validate
xxx_GET_HASH macros on dependent algorithms.

For MAC algorithms, validate the MAC size. For AEAD algorithms,
validate the tag size.

There is a separate test case for each HMAC algorithm, which is
necessary because each has its own MAC size. For other hash-dependent
algorithms, there is no interesting variation to test here, so only
one hash gets tested.

daea26f70f Correct and simplify block-based cipher modes
OFB and CFB are streaming modes. XTS is a not a cipher mode but it
doesn't use a separate padding step. This leaves only CBC as a block
cipher mode that needs a padding step.

Since CBC is the only mode that uses a separate padding step, and is
likely to remain the only mode in the future, encode the padding mode
directly in the algorithm constant, rather than building up an
algorithm value from a chaining mode and a padding mode. This greatly
simplifies the interface as well as some parts of the implementation.

ae3d2a2c26 Avoid non-standard C constructs
Don't rely on static initialization of a flexible array member, that's

8f609239d5 Do export sanity checks in import_export as well
This is not useful to validate the implementation when importing
canonical input, which is the case for most import/export test cases,
but it helps validate the sanity checks themselves.

d14664a79b Move export key sanity check from generate to exercise
Move the code to perform sanity checks on the exported key from
generate_key to exercise_key. This way the sanity checks can be
performed after importing or deriving a key as well.

In addition to checking the exported key if its usage allows it, check
the exported public key if the key is asymmetric.

9a05634558 psa_crypto_free: destroy the last slot
