If the mutex usage verification framework is enabled and it detects a
mutex usage error, report this error and mark the test as failed.
This detects most usage errors, but not all cases of using
uninitialized memory (which is impossible in full generality) and not
leaks due to missing free (which will be handled in a subsequent commit).

When using pthread mutexes (MBEDTLS_THREADING_C and
MBEDTLS_THREADING_PTHREAD enabled), and when test hooks are
enabled (MBEDTLS_TEST_HOOKS), set up wrappers around the
mbedtls_mutex_xxx abstraction. In this commit, the wrapper functions
don't do anything yet.

GCC 11 generated the warnings because the parameter `ret_buf`
was declared as `const char[10]`, but some of the arguments
provided in `run_test_snprintf` are shorter literals, like "".
Now the type of `ret_buf` is `const char *`.
Both implementations of `test_snprintf` were fixed.

The identifiers of the unmet dependencies of a test case are
stored in a buffer of fixed size that can be potentially too
small to store all the unmet dependencies. Indicate in test
report if some unmet dependencies are missing.

Fix potential buffer overflow when tracking the unmet dependencies
of a test case. The identifiers of unmet dependencies are stored
in an array of fixed size. Ensure that we don't overrun the array.

Use size_t for some variables that are array indices.
Use unsigned for some variables that are counts of "small" things.
This is a backport of commit 3c1c8ea3e7.

Warn about a gotcha that caused a bug in development.
Ensure that it's at least zeroed out, rather than uninitialized, in
non-verbose mode.

The change modifies the template code in tests/suites/helpers.function
and tests/suites/main.function so that error messages are printed to
stdout instead of being discarded. This makes errors visible regardless
of the --verbose flag being passed or not to the test suite programs.
Fixes the test suites to consistently use mbedtls_fprintf to output to
stdout or stderr.
Also redirects output from the tests to /dev/null to avoid confusing
output if the test suite code or library outputs anything to stdout.
The commit adds to the generate_code.pl script support to add #line directives
to generated code to allow build breaks to be more easily found from the
generated code.
Added a verbose option to the generated test suites which can list the
dependencies not met for skipped test cases.
Also clarifies internal interfaces between the main_test.function and test code,
and fixed a bug on calculating available tests in run-test-suites.pl.
Restructed test suite helper and main code to support tests suite helper
functions, changed C++ comments to C-style, and made the generated
source code more navigable.
Added to generate_code.pl:
- support for per test suite helper functions
- description of the structure of the files the script uses to construct
the test suite file
- delimiters through the source code to make the machine generated code
easier to understand
Our Windows implementation based on vsnprintf_s( ..., _TRUNCATE ) sometimes
writes *two* terminating NULLs. Allow for that, but obviously bytes past the
end of the buffer mustn't be touched.
- Added in each tests program to be sure they are run (putting them in a test
suite/function specific to the platform layer would cause them to be skipped
when PLATFORM_C is not defined).
- Platforms have already moved from a standard to a broken snprintf in the
past [1], so make sure to catch that if it ever happens again.

Things that are not guaranteed by the standard but should be true of all
platforms of interest to us:
- 8-bit chars
- NULL pointers represented by all-bits-zero
