64cd2f21ed Fix potential double-free in calloc selftest 
Where calloc returns two references to the same buffer, avoid calling
free() on both references by setting one to NULL.

ad2a17eb60 Uniformly use MBEDTLS_THREADING_C guards 
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.

9af413bcc5 Don't try to include mbedtls/config_*.h 
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.

186731b22a Fix warnings from clang-16 
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.
