This is automatic in CPython but not guaranteed by the language. Be friendly
to other Python implementations.

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.

Running mypy was optional for a transition period when it wasn't installed
on the CI. Now that it is, make it mandatory, to avoid silently skipping an
expected check if mypy doesn't work for some reason.

None of these options had any impact on the generated output.
Checked after turning off the HTML_TIMESTAMP option
and running sha256sum <(find . -type f -exec sha256sum {} \; | sort) in
the apidoc directory.

CCM requires one of the 128-bit-block block ciphers to be useful, just like GCM.
GCM and CCM need the cipher module.
ChaChaPoly needs ChaCha20 and Poly1305.

We had this check in the non-PSA case, but it was missing in the PSA
case.
Backport of 141be6cc7faeb68296625670b851670542481ab6 with just the
error code change to adapt to 2.28.

This can be used to validate the server's choice of group in the PSA
case (this will be done in the next commit).
Backport of 0d63b84fa49ecb758dbec4fd7a94df59fe8367ab with a very
different implementation, as 2.28 still stores the list of allowed
groups with their mbedtls_ecp group IDs, not the IANA/TLS group IDs
(changed by https://github.com/ARMmbed/mbedtls/pull/4859/ in 3.x).

The race condition mentioned in the previous commit
"Stop CMake out of source tests running on 16.04"
has also been observed with test_cmake_as_subdirectory on 3.1 and can
presumably happen on 2.28 as well. So skip it on Ubuntu 16.04 as well.
