411aee6e05 Fixes from cppcheck
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.

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.

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.
