The goal of this commit is to add some constants that can be used to
define datasets and add test data in a more readable and reusable
manner.
All platforms using ECC need to support calculations with at least 192
bits, therefore constants for this length are added. We are not using a
curve prime as those will be tested elsewhere and it is better not to
play favourites.
All platforms using RSA or FFDH need to support calculations with at
least 1024 bits, therefore numbers of this size are added too.
A safe prime is added for both sizes as it makes all elements generators
(except 0 and 1 of course), which in turn makes some tests more
effective.

We were using absolute imports under the assumption that the /scripts
directory is in the path. This worked in normal use because every one of our
Python scripts either were in the /scripts directory, or added the /scripts

However, this broke things like
```
python3 -m unittest scripts/mbedtls_dev/psa_storage.py

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:

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

Strictly speaking, the storage format checks look for regressions in

Add test cases validating that if a stored key only had the hash policy,
then after loading it psa_get_key_attributes reports that it also has the
message policy, and the key can be used with message functions.

Test keys with various persistence levels, enumerated from the
metadata tests.
For read-only keys, do not attempt to create or destroy the key
through the API, only to read a key that has been injected into
storage directly through filesystem access.
Do not test keys with a non-default location, since they require a
driver and we do not yet have a dependency mechanism to require the
presence of a driver for a specific location value.

It was used to remove the code used when mbedtls_ecp_mul() received a
NULL RNG parameter. This code is no longer relevant (as the RNG may no
longer be NULL) and will be unconditionally removed in the next commit.

When generating expressions to construct test case data, there can be
duplicate values, for example if a value of the form C(A) is present
as such in test_suite_psa_crypto_metadata.data and also constructed by
enumerating the argument A for the constructor C. Eliminate such
duplicates in generate_expressions.
This commit removes many test cases that were exact duplicates (and
were near-duplicates differing only in whitespace before the
whitespace normalization).

In macro_collector.py, base InputsForTest on PSAMacroEnumerator rather
than PSAMacroCollector. It didn't make much sense to use
PSAMacroCollector anymore since InputsForTest didn't use anything
other than the constructor.
psa_generate_tests now generates arguments for more macros.
In particular, it now collects macro arguments from
test_suite_psa_crypto_metadata. Algorithms with parameters are now
supported.

In generate_psa_tests, use InputsForTest rather than PSAMacroCollector
to gather values. This way, the enumeration of values to test includes
values used in metadata tests in addition to constructors parsed from
header files. This allows greater coverage of values built from
constructors with arguments. This doesn't make a difference yet, but
it will once algorithm constructors with arguments are supported in
generate_psa_tests.
Make the injection of numerical values optional. They are useful for
test_psa_constant_names, so keep them there. Don't use them for
not-supported tests: they might make sense, but the current code
wouldn't work since it doesn't know how to make up fake key material
or what dependencies to generate. Don't use them for storage tests:
they only make sense for supported values.
Don't inject 'PSA_SUCCESS': that's superfluous.

Changelog contents should be UTF-8 text files. So explicitly open all files as

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.

Accept Windows line endings in input files on any platform. This makes
the scripts work even when running a Unix perl with a source tree that
has Windows line endings, as happens for example on our Travis Windows
instances. This change is harmless in the common case where the input
has the platform's default line endings.

Instead of manipulating CR explicitly to cope with CRLF (Windows) line
endings in input and produce output with CRLF line endings, just
convert files from/to CRLF line endings when reading/writing.
The minimum required Perl version remains 5.8, since this both the
version that introduced Digest::MD5 (which was used before this patch)
and the version that introduced open "<:crlf" (which this patch
introduces).

Although SHA512 is currently required to enable SHA384, this

The previous implementation of the error addition interface did not comply
with the invasive testing architecture guidelines. This commit fixes that
by:
- Renaming functions/macros/variables to follow the mbedtls_error_xxx or
mbedtls_test_hook_xxx convention.
- Making mbedtls_test_hook_error_add a global variable that can be set
by the testing code.
- Using a static inline function call, as opposed to macro, to keep
discrepancies between debug and production version to a minimum.

`error.c` and error.h are the more logical place to keep this code and it
prevents issues with building `common.c` and conflicts with other projects
that use mbedtls (such as mbedOS).

`error.fmt` and then running `./scripts/generate_errors.pl`.
