kdf.c: wc_PRF() - No need for previous, reuse current.
sha256.c: Transform_Sha256() - Add slow but small version for many
register implementation.
sp_int.h: Change 'used' and 'size' fields to 16-bit types when possible.
sp_int.c: Fixes for 16-bit used.
Tested with `./configure --disable-asm --enable-32bit --enable-asn=original --enable-cryptonly CFLAGS="-Wconversion -pedantic" && make`. Some progress with ASN template, but not complete.
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.

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 compilation warning
* adjust SHA3-384 test error-codes
The way the codes were constructed before, they were not unique.
* unify code
Instead of having `ifdef`'s in the code, define our own wrapper around
the keysource as required.
* add CMake option for help-text in wolfCrypt tests
* expose test `main()` as `wolfcrypt_test_main()`
* Don't overwrite previously set errors
* add FreeRTOS support for Xilinx demo
* move `fp_reverse` from `tfm.c` to `wolfmath.c` and rename to
`mp_reverse`.

Check size passed to mp_init_size() 1..SP_INT_DIGITS.
More checks of parameters to SP int functions to ensure result is big
enough to hold value calculated.
Fix mask type in mp_cond_copy to be at least 16 bits to handle 'used'
being larger than 8-bit but mp_digit being 8-bit.
When large numbers are used with 8-bit words, mul/sqr partial sums will
overflow a word. Fix implementations to handle this.
Added PRIVATE_D version of rsa private key operation for SP
implementation for specific platforms.
WC_NO_RNG results in warnings when RNG calls don't do anything.
Added ifdef checks for variables not used otherwise.
Remove superfluous if statements like when checking ret == 0.
Change names of globals that are generic and are used locally before
global definition.
Remove definition of variable len that isn't used except as a
replacement for sz which is parameter.
Don't subtract two variables when one has just been assigned the value
of the other.
Fix shifting of signed value.
Fix parameter checking in aes.c and des3.c for platform specific code.
* Fix for possible NULL RNG case in mp_rand.
* Fix for memory macros to handle expression for `HEAP`.
* Fix for possible unknown uint32_t type with mem track.
* Fix for double Alloc/Free print when using track and debug memory at same time.
* Fix for building with `./configure CFLAGS="-DECC_USER_CURVES -DNO_ECC256 -DHAVE_ECC160"`
* Performance improvements for cases with `WC_ASYNC_NO_HASH` and `WC_ASYNC_ENABLE_SHA256`.
More places to mask shifted n.
Fix conditional check on NO_3072 in sp_int.h
Disable prime checking when using SP maths.
Add support for mp_tohex to SP maths.
Fix wolfmath.c to support including SP maths.
* Added support for ECC, AES-GCM and HMAC (SHA-224 and SHA3).
* Fixes for Nitrox V with TLS.
* ECC refactor for so key based `r` and `s` apply only when building with `WOLFSSL_ASYNC_CRYPT`.
* ECC refactor for `e` and `signK` to use key based pointer for Nitrox V.
* Improved the Nitrox V HMAC to use start, update and final API's instead of caching updates.
* Fix for Intel QuickAssist with unsupported HMAC hash algos using `IntelQaHmacGetType` (such as SHA3).
* Added new API `wc_mp_to_bigint_sz` to zero pad unsigned bin.
* Fix for AES GCM to gate HW use based on IV len in aes.c and remove the gate in test.c.
* Implemented workaround to use software for AES GCM Nitrox V hardware and 13 byte AAD length for TLS.
* New debug option `WOLFSSL_NITROX_DEBUG` to add pending count.
