'mbedtls_pk_psa_rsa_sign_ext' function allocates a buffer of maximum
size 5679 bytes (MBEDTLS_PK_RSA_PRV_DER_MAX_BYTES) on the stack to store
DER encoded private key. This increased stack usage significantly for
RSA signature operations when MBEDTLS_PSA_CRYPTO_C is defined.
This issue was discovered when adding support for EAP-TLS 1.3 (rfc9190).

The result format for code size comparison is:
filename new(text) new(data) change(text) change(data)
yyy.o xxx xxx xx xx
The numbers followed are in bytes.

Percentage is not a useful number when looking at code size changes.
Since it depends on the base of the code size. It might give
misleading information by simply looking at the numbers.

Running clang-16 on mbedtls reports warnings of type "-Wstrict-prototypes".
This patch fixes these warnings by adding void to functions with no
arguments. The generate_test_code.py is modified to insert void into test
functions with no arguments in *.function files.

The Ubuntu 16.04 and 22.04 docker images have been updated with
earliest and latest versions of gcc and clang respectively.
This patch adds the necessary component and support functions
required for the CI to run these compilers.
For FreeBSD we invoke the function by name so a condition is added
to disable the existing test_clang_opt function for linux.

We had information in both README.md and CONTRIBUTING.md about Mbed TLS licensing,
but the information in CONTRIBUTING.md was missing that authors still need to
accept that their contributions may be distributed under both Apache 2.0 and
GPLv2-or-later.
Move all but the most high-level “Mbed TLS files are provided under the
Apache-2.0 license” statement to CONTRIBUTING.md, and tidy up the text a bit.

- RSA was missing the MBEDTLS_ prefix.
- DH needs the same temporary fix (prefix + suffix) for now.
- hack_dependencies_not_implemented() needs to ignore MBEDTLS_PSA_WANT
dependencies.
While at it, make the code currently used for ECC more generic, so that
it's ready to be used for RSA and DH in the near future.

If we use option --stdout, the logging level is set as
logging.ERROR. But --verbose is able to overwrite logging level as
logging.INFO if we want to display intermediate log in the process
of code size comparison.
