cc880e39ae Add deterministic ECDSA sig gen. Fix corner cases for add point.
In verify, two points are added and they may either be the same point
(different z) or result in infinity.
If they are the same point then a double needs to be performed instead.
Detection of infinity added.
Calculation of wc_ecc_sig_size fixed to handle wehn there are more bits
in the order than in the modulus.

901ee627fc Fixes from using cppcheck tool
Various fixes for uninitialized variable use.
sniffer.c: close file when seek fails
tls.c: fix QSH_GET_SIZE macro
wolfio.c: uIPGenerateCookie: use the parameter, _ctx, instead of self
referencing.
wolfssl_adds.c: check for equivalent to XBADFILE to indicate error.
SP: change right shift of signed value to unsigned
sp_int.h: define 128-bit types
types.h: change a XMALLOC define to not use (,,) - cppcheck doesn't like
it and is unnecessary.

necessary).

1792fe34b9 Fix precomputation tables to not include infinity field.
Fixes to ARM code
- put in it instruction before conditional for old compilers.
- fix small code size version of compare
- handle not being able to shift by the full size - want result to be
zero
Casts as required by compiler to reduce bit size explicitly.

074e770c98 * Fix to ensure user_settings.h can be included for bio.c and evp.c when IDE or compiler tries to build it directly. Allows for wildcard .c include along with WOLFSSL_IGNORE_FILE_WARN.
* Fix for building SP cortex M without RSA.
* Fix for type-cast warning with STSAFE-A100.
* Improved the RNG seed test to prevent type-case warning.
