in the call to psa_aead_verify() and 2) why the test of
.hits_finish is always 0 in this test case.

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().

Validate the size macros directly from the output length in the test data,
rather than using the value returned by the library. This is equivalent
since the value returned by the library is checked to be identical.
Enforce that SIZE() <= MAX_SIZE(), in addition to length <= SIZE(). This is
stronger than the previous code which merely enforced length <= SIZE() and
length <= MAX_SIZE().

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.

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.

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.

`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).

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.

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.

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.

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.

Store the TLS version instead of minor version number in tls_version.
Note: struct member size changed from unsigned char to uint16_t
Due to standard structure padding, the structure size does not change
unless alignment is 1-byte (instead of 2-byte or more)
Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is compatible on little-endian platforms,
but not compatible on big-endian platforms. The enum values for
the lower byte of MBEDTLS_SSL_VERSION_TLS1_2 and of
MBEDTLS_SSL_VERSION_TLS1_3 matches MBEDTLS_SSL_MINOR_VERSION_3 and
MBEDTLS_SSL_MINOR_VERSION_4, respectively.
Note: care has been taken to preserve serialized session format,
which uses only the lower byte of the TLS version.

`curves.pl` (invoked by `all.sh test_depends_curves`, and
`all.sh test_depends_curves_psa`) currently runs two series of tests:
* For each curve, test with only that curve enabled.
* For each curve, test with all curves but that one.
Originally this script was introduced to validate test dependencies, and for
that all-but-one gives better results because it handles test cases that
require multiple curves. Then we extended the script to also test with a
single curve, which matches many real-world setups and catches some product
bugs. Single-curve testing also validates test dependencies in a more
limited way.
Remove all-but-one curve testing, because it doesn't add much to the test
coverage. Mainly, this means that we now won't detect if a test case
declares two curve dependencies but actually also depends on a third. This
is an acceptable loss.
The trigger for removing all-but-one curve testing is that this will make
the job take only about half as long, and the length of the job was a bit of
a problem. Resolves#5729.

component_test_CID_no_debug was added specifically to be a non-regression
test for https://github.com/Mbed-TLS/mbedtls/issues/3998. Running compat.sh
in the newly introduced config-ccm-psk-dtls1_2.h is also a non-regression
test for that bug. Therefore component_test_CID_no_debug is redundant for
its primary purpose.
Of course every configuration is different, but the additional coverage from
component_test_CID_no_debug is minimal, unlike config-ccm-psk-dtls1_2.h
which is a plausible real-world configuration.
In mbedtls-2.28, component_test_CID_no_debug was never added, and running
the unit tests in that configuration does not trigger the #3998 bug, only
compat.sh does. So, rather than backport component_test_CID_no_debug to
2.28.2, I am removing it from 3.2.

When the client or server uses a specific protocol version, automatically
require that version to be enabled at compile time.
An explicit call is still needed in test cases that require a specific
protocol version (due to analyzing version-specific behavior, or checking
the version in logs), but do not force that specific protocol version, or that
force a specific version only on the openssl/gnutls side.
