Where calloc returns two references to the same buffer, avoid calling
free() on both references by setting one to NULL.

Now that library is in the include path when compiling metatest.c, don't
duplicate the definition of __func__ from library/common.h.

Asan poisons memory with an 8-byte granularity. We want to make sure that
the whole specified region is poisoned (our typical use case is a
heap-allocated object, and we want to poison the whole object, and we don't
care about the bytes after the end of the object and up to the beginning of
the next object). So align the start and end of the region to (un)poison to
an 8-byte boundary.

While an area of memory is poisoned, reading or writing from it triggers a
sanitizer violation.
Implemented for ASan.

Since the code compiles with MBEDTLS_THREADING_C, not just with
MBEDTLS_THREADING_PTHREAD, use MBEDTLS_THREADING_C as the guard. The runtime
behavior is only as desired under certain conditions that imply
MBEDTLS_THREADING_PTHREAD, but that's fine: no metatest is expected to pass
in all scenarios, only under specific build- and run-time conditions.

This program can be used to validate that things that should be detected as
test failures are indeed caught, either by setting the test result to
MBEDTLS_TEST_RESULT_FAILED or by aborting the program.

In case of an out-of-tree build with the CMake build
system the path to crypto_config.h has to be defined
as the path to mbedtls_config.h. Add this possibility
tp generate_query_config.pl.

They're included by build_info.h and must not be included directly.
Currently, this only concerns one file: config_psa.h. It's technically a bug
to include it, but a harmless one because that header has already been
included by build_info.h except in configurations where it
effectively had no effect (enabling PSA options with PSA turned off).
We plan to split config_psa.h into multiple headers that are less
independent, which could make the inclusion more problematic.

Running clang-16 on mbedtls reports warnings of type "-Wstrict-prototypes".
This patch fixes these warnings by adding void to functions with no
arguments. The generate_test_code.py is modified to insert void into test
functions with no arguments in *.function files.
