For calls to gnutls-serv and gnutls-cli where --priority is not
specified, explicitly add the default value: --priority=normal. This is
needed for some tests on Ubuntu 20.04 (gnutls 3.6.13).
For example:
./ssl-opt.sh -f "DTLS fragmenting: gnutls.*1.0"
requires this PR to work on Ubuntu 20.04

We care about the exit code of our server, for example if it's
reporting a memory leak after having otherwise executed correctly.
We don't care about the exit code of the servers we're using for
interoperability testing (openssl s_server, gnutls-serv). We assume
that they're working correctly anyway, and they return 1 (gnutls-serv)
or die by the signal handle the signal (openssl) when killed by a
signal.

In psa_generate_derived_key_internal() an error case was returning
directly rather than jumping to the exit label, which meant that an
allocated buffer would not be free'd.

Make sure MBEDTLS_PSA_CRYPTO_CLIENT is defined
when MBEDTLS_PSA_CRYPTO_C is defined and guard
PSA client code only with MBEDTLS_PSA_CRYPTO_CLIENT.
The definition of MBEDTLS_PSA_CRYPTO_CLIENT is done
in crypto_types.h before the definition of
psa_key_attributes_t. That way as PSA crypto client
code is related to key attributes we can be quite
confident that MBEDTLS_PSA_CRYPTO_CLIENT will be
defined when needed.

Move test macros previously located in `suites/helpers.function` to
`include/test/macros.h`. This makes these test infrastructure macros
available for use in other parts of the test infrastructure at compile
time as opposed to run time.
This commit is a simple cut and paste from one file to the other.

Check that the source address and the frame counter have the expected
length. Otherwise, if the test data was invalid, the test code could
build nonsensical inputs, potentially overflowing the iv buffer.
The primary benefit of this change is that it also silences a warning
from compiling with `gcc-10 -O3` (observed with GCC 10.2.0 on
Linux/amd64). GCC unrolled the loops and complained about a buffer
overflow with warnings like:
```
suites/test_suite_ccm.function: In function 'test_mbedtls_ccm_star_auth_decrypt':
suites/test_suite_ccm.function:271:15: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
271 | iv[i] = source_address->x[i];
| ~~~~~~^~~~~~~~~~~~~~~~~~~~~~
suites/test_suite_ccm.function:254:19: note: at offset [13, 14] to object 'iv' with size 13 declared here
254 | unsigned char iv[13];
```
Just using memcpy instead of loops bypasses this warnings. The added
checks are a bonus.

The test function generate_random allocated a few extra bytes after
the expected output and checked that these extra bytes were not
overwritten. Memory sanity checks such as AddressSanitizer and
Valgrind already detect this kind of buffer overflow, so having this
test in our code was actually redundant. Remove it.
This has the benefit of not triggering a build error with GCC
(observed with 7.5.0 and 9.3.0) when ASan+UBSan is enabled: with the
previous code using trail, GCC complained about an excessively large
value passed to calloc(), which was (size_t)(-sizeof(trail)).
Thus this commit fixes#4122.

Attempting to create an ECC key with a curve specification that is not
valid can plausibly fail with PSA_ERROR_INVALID_ARGUMENT ("this is not
a curve specification at all") or PSA_ERROR_NOT_SUPPORTED ("this may
be a curve specification, but not one I support"). The choice of error
is somewhat subjective.
Before this commit, due to happenstance in the implementation, an
attempt to use a curve that is declared in the PSA API but not
implemented in Mbed TLS returned PSA_ERROR_INVALID_ARGUMENT, whereas
an attempt to use a curve that Mbed TLS supports but for which support
was disabled at compile-time returned PSA_ERROR_NOT_SUPPORTED. This
inconsistency made it difficult to write negative tests that could
work whether the curve is implemented via Mbed TLS code or via a
driver.
After this commit, any attempt to use parameters that are not
recognized fails with NOT_SUPPORTED, whether a curve with the
specified size might plausibly exist or not, because "might plausibly
exist" is not something Mbed TLS can determine.
To keep returning INVALID_ARGUMENT when importing an ECC key with an
explicit "bits" attribute that is inconsistent with the size of the
key material, this commit changes the way mbedtls_ecc_group_of_psa()
works: it now works on a size in bits rather than bytes, with an extra
flag indicating whether the bit-size must be exact or not.

Test random generation as a whole. This is different from
test_suite_*_drbg and test_suite_entropy, which respectively test PRNG
modules and entropy collection.
Start with basic tests: good-case tests, and do it twice and compare
the results to validate that entropy collection doesn't repeat itself.
