Include more curves. For example, the Brainpool curves don't have
dedicated "mod p" reduction routines, so they have a much larger number
of allocs (comparable to the NIST curves with `MBEDTLS_ECP_NIST_OPTIM`
disabled).
On the other hand, to keep the script's running time reasonable, remove
a few things:
- curves smaller than 256 bits (out of favour these days)
- window sizes larger than the default: 6 was particularly useless as
it's never selected by the current code; 5 can only be selected with
curves >= 384 and is unlikely to be used in practice as it increases
heap usage quite a lot for very little performance gain.

Clearly the intention was to enable it, as ECDSA_C was defined, but the
benchmark also requires SHA-256 for ECDSA.
Also, specify "ecdh ecdsa" when invoking the benchmark program, in order
to avoid spurious output about SHA-256.

MBEDTLS_HAVE_TIME is documented as: "System has time.h and time()."
If that is not defined, do not attempt to include time.h.
A particular problem is platform-time.h, which should only be included if
MBEDTLS_HAVE_TIME is defined, which makes everything messier. Maybe it
should be refactored to have the check inside the header.

The storage format comparison has a dual purpose: detect format changes that
lead to a loss of backward compatibility, and detect loss of test coverage.
For loss of backward compatibility, the read tests are the relevant ones.
For loss of test coverage, all generated test cases are potentially
relevant, but this script currently focuses on storage format (where a loss
of test coverage may be a symptom of a loss of backward compatibility).
Therefore, storage format test comparison now looks at manually written
storage format tests, but only if they're read tests.

Expand abi_check.py to look for backward incompatibilities not only in
the interface exposed to application code (and to some extent driver
code), but also to the interface exposed via the storage format, which
is relevant when upgrading Mbed TLS on a device with a PSA keystore.
Strictly speaking, the storage format checks look for regressions in
the automatically generated storage format test data. Incompatible
changes that are not covered by the generated tests will also not be
covered by the interface checker.
A known defect in this commit is that the --brief output is not brief
for storage format checks.

This way we can add other checks and only run a subset of all the
checks. The default remains to run all the checks.
I made separate options for API and ABI, but since we use the same
tool for both and it doesn't have an obvious way to check only API or
only ABI, the two options must be both enabled or both disabled.

Changelog contents should be UTF-8 text files. So explicitly open all files as
UTF-8. This makes the script independent of the ambient locale (except with
respect to exception messages, but we can live with that).

Changelog contents should be UTF-8 text files. There's no need to be
binary-safe. So switch to using text strings in Python (str, not bytes). This
commit makes the following changes:
* Bytes literals (b'…') to string literals ('…').
* Subprocess output (which is all git information) is decoded as ascii.
* Inject text directly in exceptions rather than calling a decode method.
This is enough to make the script work as desired in a UTF-8 locale.

Add pip requirements files. We'll have separate requirements files for
different target audiences. Each file can use `-r` lines to include other

This commit adds two requirement files: one with everything that's needed to
pass the CI, and one with additional tools that are suggested for Mbed TLS
maintainers to install locally.

This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.
In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).
Changes in this commit:
* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
generate_psa_constant_names).

Before this commit, definitions of error codes must match a strict pattern,
with a Doxygen comment following the definition on the same line and
starting with "/**<". Change how generate_errors.pl so that the Doxygen
comment can be before the definition instead of after, and doesn't have to
be on the same line.
Also allow spaces between "#" and "define", and allow Doxygen comments to
start with "/*!" rather than "/**". Starting with "///" or "//!" is not
supported.
This commit does not change the output of generate_errors.pl.
