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.

component_test_cmake_out_of_source was running the ssl-opt.sh test case

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.

`PSA_ALG_AEAD_WITH_SHORTENED_TAG(aead_alg, len) == aead_alg` when

This fixes one test case due to the way arguments of

There's nothing wrong with ECC keys on Brainpool curves,

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.

`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
