Instead of fully validating beforehand
signature algorithms with regards to the
private key, do minimum validation and then
just try to compute the signature. If it
fails try another reasonable algorithm if any.

When selecting the server certificate based on
the signature algorithms supported by the client,
check the signature algorithms as close as possible
to the way they are checked to compute the
signature for the server to prove it possesses
the private key associated to the certificate.
That way we minimize the odds of selecting a
certificate for which the server will not be
able to compute the signature to prove it
possesses the private key associated to the
certificate.

Stating from the default config means a few things are implicitly
excluded; starting from the full config makes it all fully explicit.

CMakeLists.txt was calling generate_psa_tests.py and siblings to list the
generated test data files with a --directory option, intended the output to
be this argument textually. This used to work, but no longer does, because
the --directory argument is relative to the current directory when the
Python script is invoked, and the script now shows an absolute path.
CMakeLists.txt now completely ignores the directory part of the listed data
file paths and builds its own. The base_xxx_files variables now contain
actual base names, without a "suites/" prefix. This makes it more robust
with respect to the behavior of the Python script, but it will break if
we put data files in multiple different directories one day.

When pylint runs in parallel, it loses the ability to detect duplicated code
across modules. Duplicated code is usually a bad thing, so give pylint the
opportunity to let us know.
This makes pylint slightly slower, but going from 2 threads to 1 does not
make it anywhere close to twice as slow. On my machine, with Python 3.5,
pylint -j2 takes about 12s while single-threaded pylint takes about 16s
of wall clock time.

We had 4 identical copies of the check_repo_path function. Replace them by a
single copy in the build_tree module where it naturally belongs.

mbedtls_vsnprintf replacement works like mbedtls_snprintf replacement, so
copy the requirements for MBEDTLS_PLATFORM_VSNPRINTF_ALT.
(MBEDTLS_PLATFORM_xxx_MACRO shouldn't require MBEDTLS_PLATFORM_C, but that's
a separate preexisting problem which I do not try address at this time.)

We have Python code both for test code generation
(tests/scripts/generate_test_code.py) and now for test data generation.
Avoid the ambiguous expression "test generation".
This commit renames the Python module and adjusts all references to it. A
subsequent commit will adjust the documentation.

Previous changes used the docstring of the test_generation module,
which does not inform a user about the script.

As a public header, it should no longer include common.h, just use
build_info.h which is what we actually need anyway.

Initializing return status variables to CORRUPTION_DETECTED is a second line
of defense in library code in case there's a code path where we forget to
assign to the variable. This isn't useful in test code. In any case, here,
we might as well define the variable at the point of use.
This fixes a build error in configurations with MBEDTLS_ERROR_C and
MBEDTLS_PSA_CRYPTO_C both disabled, because then mbedtls/error.h isn't
included so MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED isn't defined.

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:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')
```
