3d67365ef7 Add a key_buffer_length output to "get_builtin_key"
While builtin keys will often have a fixed-size context, this is not
necessarily the case, so the "get_builtin_key" entry point needs to
return the size of the actual key context.

1af872d23b Move the fake PSA external RNG to its own header and source files
Move the declaration of the functions needed to use the test
implementation of mbedtls_psa_external_get_random() to a new header
file. Before, they were declared in
tests/include/test/psa_crypto_helpers.h, but this header file can't be
included in sample programs because it also includes headers from the
library directory which is not on the include path for sample
programs.

This fixes the build of the sample programs when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are
enabled.

Move the implementation of the functions to a separate .c file as
well. This isn't strictly necessary, but makes the structure of the
source code easier to understand.

e1d51bd99d Depend on all test headers when building tests
There were explicit dependencies on header files for some test suites,
dating back from when only a few test suites depended on anything in
tests/include. The noted dependencies were still correct, but now that
tests/include is more populated, they were only the tip of the
iceberg. Just keep it simple and depend on all the headers.

Adds the `mbedtls_` prefix to `test_result_t` and `test_info` and updates
any references to them. This is to follow the naming convention as these are

9634bb10d9 Move helper testing functions to tests/src/helpers.c
Moves the functions `test_fail`, `test_set_step`, `test_skip` and the struct
`test_info` from `tests/suites/helpers.function` to `tests/src/helpers.*`.
This is done to open these functions up to the API where they can be used by
other functions in the 'src' test infrastructure module.

As the functions are now contained within the src folder of the testing
infrastructure, the `mbedtls_` prefix has been added to the functions.

2146211204 SSL test programs: enable the PSA test external RNG
Currently, MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG is tested with a dummy
insecure implementation of mbedtls_psa_external_get_random. This
function needs to be explicitly enabled at runtime. This needs to
happen when the PSA external RNG is used, which currently is the case
in SSL test programs only when MBEDTLS_USE_PSA_CRYPTO is enabled.

c85c20147b Don't call TEST_ASSERT in PSA_DONE
TEST_ASSERT jumps to the exit label, so it must not be called from
cleanup code executed after the exit label. It's legitimate (and
indeed very common) to call PSA_DONE in cleanup code, so PSA_DONE must
not jump to exit.

Define an auxiliary function test_fail_if_psa_leaking() that calls
test_fail() with the error message provided by
mbedtls_test_helper_is_psa_leaking(). This function currently needs to
be in helpers.function rather than in a PSA-specific helper file
because it calls test_fail which is defined in helpers.function.

6beb327a5e external_rng_failure_sign: more robust buffer management
Don't microoptimize memory usage in tests: use separate buffers for
the input and the output. Allocate the input buffer dynamically
because the size is a parameter of the test case. Allocate the output
buffer dynamically because it's generally good practice in tests so
that a memory sanitizer can detect a buffer overflow.
