We do not intend to support multithreaded testing in 2.28, so
introducing a C11 feature here is an unnecessary burden.

This allows unusually-nested memory poisoning to work correctly, since
it keeps track of whether any buffers are still poisoned, rather than
just disabling poisoning at the first call to the UNPOISON() macro.

Allow memory poisoning to be enabled and disabled at runtime using a
thread-local flag. This allows poisoning to be disabled whenever a PSA
function is called but not through the test wrappers, removing false
positive use-after-poisons.

`psa_collect_statuses.py` runs `make RECORD_PSA_STATUS_COVERAGE_LOG=1`,
which builds with `RECORD_PSA_STATUS_COVERAGE_LOG`. In this mode, the build
includes wrappers for PSA functions, which conflict with the newly
introduced wrappers that are enabled whenever `MBEDTLS_TEST_HOOKS` is
enabled. In the future, the collect-statuses mechanism should use the new
generic wrapper mechanism. For the time being, keep the old wrappers and
avoid the new wrappers when doing the collect-statuses build.

Commit files generated by `tests/scripts/generate_psa_wrappers.py`. As of
this commit, the new code is neither useful (the wrappers just call the
underlying functions) nor used (the wrapper functions are not called from
anywhere). This will change in subsequent commits.

Make sure that we don't enable memory poisoning when
MBEDTLS_PSA_COPY_CALLER_BUFFERS is disabled.

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.

The seed file must exist before running tests. Because the location is
somewhat platform- and configuration-dependent, and to be friendly to
developers who run test suites individually and aren't familiar with this
feature, rely on the test framework code rather than on test scripts to
create the seed file.

The build option MBEDTLS_PSA_INJECT_ENTROPY requires some extra platform
functions, for historical reasons. To enable us to test this option, provide
a version of these functions for testing.
(These versions would actually work in production, but providing them in the
library in a way that doesn't break existing users might be slightly tricky,
so it's out of scope of this commit.)

ssl_helpers.c is treated with W3 warning level in MSVC complier.
So that it's reported as error for warning of conversion from
size_t to int. This change fixes all this type of warning seen in
Microsoft Visual Studio 12.0. Besides, some potential problems of
type conversion are also handled.

During test of component build_arm_linux_gnueabi_gcc_arm5vte and
build_arm_none_eabi_gcc_m0plus. It fails with
- error: implicit declaration of function
‘test_fail_if_psa_leaking’
It happens because test_fail_if_psa_leaking is defined in
helpers.function. This block of code is not converted into C code
while compiling ssl_helpers.c. The function has been moved to
psa_crypto_helpers.c in order to fix this build error.

tests/src/ssl_helpers.c depends on functions defined
in library/*.c. If it's complied as an OBJECT with other c files,
cmake complains undefined reference in link stage under programs/.
Therefore, tests/src/test_helpers/ is created to hold c files with
dependency of library/*.c. Besides, tests/src/test_helper/*.c is
separated into another OBJECT, mbedtls_test_helpers, as sources
to build all test suite executables.
In addition, everest header directory is included in case
MBEDTLS_ECDH_VARIANT_EVEREST_ENABLED is enabled.

Since we move many functions from test_suite_ssl.function to
ssl_helpers.c in commit bd56b03. This causes various of
build errors. This commit fixes all the build errors by
- including header files
- providing function definition
- adding guards for typedef statements and functions

Some functions are renamed in commit c463849. This change moves all
those functions which are used to set up a TLS connection from
test_suite_ssl.function into ssl_helpers.c.

test_suite_ssl.function contains many functions that are used to set
up a TLS connection. To reduce its file size, those functions would
be moved to ssl_helpers.c under tests/src. As the start of this
implementation, some necessary header files are moved in advance.
