63eb28c728 Use separate counters for 8-fold and single multiplication steps
Compilers are likely to generate shorter assembly for loops of the
form `while( cnt-- ) { ... }` rather than
`for( ; count >= X; count -= X ) { ... }`. (E.g. the latter needs
a subtract+compare+branch after each loop, while the former only
needs decrement+branch).

5bd0b51048 Use terse output from lsof
This both simplifies parsing a little, and suppresses warnings. Suppressing
warnings is both good and bad: on the one hand it resolves problems such as
https://github.com/Mbed-TLS/mbedtls/issues/5731, on the other hand it may
hide clues as to why lsof wouldn't be working as expected.

a841c2a20f test_cmake_out_of_source: run an ssl-opt test case that exists
component_test_cmake_out_of_source was running the ssl-opt.sh test case
"Fallback SCSV: beginning of list", but this test case was removed in Mbed
TLS 3.0, so ssl-opt.sh was running nothing, which is not an effective test.
In 2.x, the test case was chosen because it uses an additional auxiliary
program tests/scripts/tcp_client.pl. This auxiliary program is no longer
used. So instead, run at least one test case that's sure to exist.

6e0f80ab94 Don't try to perform operations when driver support is lacking
We test some configurations using drivers where the driver doesn't
support certain hash algorithms, but declares that it supports
compound algorithms that use those hashes. Until this is fixed,
in those configurations, don't try to actually perform operations.

The built-in implementation of asymmetric algorithms that use a
hash internally only dispatch to the internal md module, not to
PSA. Until this is supported, don't try to actually perform
operations when the operation is built-in and the hash isn't.

17e350b12a Short-tag AEAD with the nominal length are encoded as nominal AEAD
`PSA_ALG_AEAD_WITH_SHORTENED_TAG(aead_alg, len) == aead_alg` when
`len == PSA_AEAD_TAG_LENGTH(aead_alg)`. So skip this case when testing
the printing of constants.

This fixes one test case due to the way arguments of
`PSA_ALG_AEAD_WITH_SHORTENED_TAG` are enumerated (all algorithms are tested
for a value of `len` which isn't problematic, and all values of `len` are
tested for one algorithm).

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.

ac17ec4388 Public keys can't be used as private-key inputs to key agreement
The PSA API does not use public key objects in key agreement
operations: it imports the public key as a formatted byte string.
So a public key object with a key agreement algorithm is not
a valid combination.

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.

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.

e3a0890e4f Reject invalid MAC and AEAD truncations
Reject algorithms of the form PSA_ALG_TRUNCATED_MAC(...) or
PSA_ALG_AEAD_WITH_SHORTENED_TAG(...) when the truncation length is invalid
or not accepted by policy in Mbed TLS.

This is done in KeyType.can_do, so in generate_psa_tests.py, keys will be
tested for operation failure with this algorithm if the algorithm is
rejected, and for storage if the algorithm is accepted.

d78c59c0de Test more truncated MAC and short AEAD tag lengths
The current macro collector only tried the minimum and maximum expressible
lengths for PSA_ALG_TRUNCATED_MAC and PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG.
This was good enough for psa_constant_names, but it's weak for exercising
keys, in particular because it doesn't include any valid AEAD tag length.
So cover more lengths.

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.
