Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
* Add introspection for math build.
* Raise build error if more than one multi-precision math library used.
* Fix ESP32 to support using any multi-precision math option.
* Refactor math headers to use `wolfmath.h`
* Refactor of the opaque math variable type `MATH_INT_T` used by crypto hardware (QuickAssist, SE050, ESP32 and STM32).
* Cleanups for building with `WOLFCRYPT_ONLY` and `NO_BIG_INT`.
* Stop forcing use of fast math by default for platforms in settings.h. Note: For users that still want to use fast math (tfm.c) they will need to add USE_FAST_MATH to their build settings.

* wolfcrypt/test/test.{c,h}: refactor to capture and encode error retvals using WC_TEST_RET_*() macros (based on line numbers), and print line and return code in err_sys().
* wolfcrypt/test/test.h: cast back to int in WC_TEST_RET_ENC(), to fix MSVC warning.
* configure.ac: add shake128 and shake256 to enable-all and enable-all-crypto;
* wolfcrypt/benchmark/benchmark.c: fix gating for bench_shake128() from !defined(WOLFSSL_NO_SHAKE128) to defined(WOLFSSL_SHAKE128).
* wolfcrypt/test/test.h: add WC_TEST_RET_TAG_* and WC_TEST_RET_DEC_TAG(), and refactor WC_TEST_RET_{ENC,DEC}_*() macros to implement the tag mechanism;
* add render_error_message() with tag-specific rendering of error strings;
* wolfcrypt/test/test.c: smallstack refactor of shake128_test() and shake128_absorb_test();
* wolfcrypt/test/test.c: change gating around mp_test() and related routines from defined(HAVE_VALGRIND) to defined(WOLFSSL_PUBLIC_MP);
* smallstack refactor of mp_test();
* refactor a slew of WC_TEST_RET_ENC_NC associated with XFOPEN/XFREAD to be WC_TEST_RET_ENC_ERRNO, and add error detection for XFREAD (previously silently tolerating zero retvals).
* wolfcrypt/test/test.c: build mp_test() only if WOLFSSL_SP_MATH_ALL or USE_FAST_MATH (in addition to WOLFSSL_PUBLIC_MP), because many general purpose functions such as sp_mulmod() are gated out in SP builds without WOLFSSL_SP_MATH_ALL.
* wolfcrypt/test/test.c: fix array bounds flubs in shake128_test();
* don't print_fiducials() in wolfcrypt_test() header, but rather, after render_error_message() in err_sys().
* wolfcrypt/test/test.{c,h}: wrap some overlong lines, and fix an unused-variable warning in mp_test_set_is_bit().
* wolfcrypt/test/test.c: fixes for several misplaced and several missing WC_TEST_RET_ENC_EC()s.
* set the client state correctly when wc_ecc_ctx_set_kdf_salt is called
* add test that covers wc_ecc_ctx_set_kdf_salt
* use shared key and smallstack to reduce test stack usage
used and size have no reason to be negative - change type.
Change code to match unsigned change. Mostly change variables to be
unsigned where possible.
integer.c: Only have mp_rand_prime available when needed and
mp_prime_is_prime_ex is available.
Fixes from regression testing.
fix file descriptor leaks in AF_ALG code, and fix return codes (WC_AFALG_SOCK_E, not -1) in afalg_aes.c;
fixes for sanitizer-detected forbidden null pointer args in AfalgHashUpdate() and AfalgHashCopy();
fixes for resource leaks in api.c test_wolfSSL_AES_cbc_encrypt() (missing wc_AesFree()s);
fixes for resource leaks in test.c openssl_test() (missing wolfSSL_EVP_CIPHER_CTX_cleanup());
also some local fixes for bugprone-signed-char-misuse, readability-redundant-preprocessor, and clang-diagnostic-strict-prototypes, in src/pk.c and src/ssl.c.
* Fix for STM32 Hash peripherals (like on F437) with FIFO depth = 1.
* Cleanups for `XREALLOC` and new `WOLFSSL_NO_REALLOC` to force undef of `XREALLOC`.
* Change STM32 Cube to default to `NO_TLS_UART_TEST`.
mp_to_unsigned_len checks length and front pads with zeros.
Return MP_VAL when length is too small in all implemenations.
Make TFM implementation check length.
Add test case.
* Fixed `PEM_BUFSIZE` macro redefined when building with coexist.
* Updated the `user_settings_all.h` and `user_settings_wolfboot_keytools.h` to include latest options.
* Improved API unit test error case checking where `TEST_RES_CHECK` is not used.
* Changed `TEST_SKIPPED` to unique value.
* Added CI tests for enable-all, small stack, and user setting templates.
Enabling SP with ASM didn't enable SP or error out when SP wasn't
configured. Now enables SP when '' and errors when 'no'.
SAKKE modinv used large amounts of stack. Change to have more temporary
memory allocated increased to cover the usage.
ECC, SAKKE: sp_<bits>_ecc_mulmod_<cpu><words>() used large amounts of
stack. Allocate when WOLFSSL_SMALL_STACK.
wc_DhCheckKeyPair() not available when HAVE_SELFTEST.
Wasn't compiled in before as WOLFSSL_HAVE_SP_DH wasn't defined.
