4f44df96dc MP: integer OOB write fix 
mp_to_unsigned_bin_len() now checks length passed in is greater than or
equal length to write.

9ef9671886 ECC uses CT vers of addmod, submod and div_2_mod 
The TFM implementations of mp_submod_ct, mp_addmod_ct,
mp_div_2_mod_t are more resilient to side-channels.

ddad95d52c mp_sub_d (integer.c): return error when digit is too big 
Code can't handle subtracting a number (an mp_digit) larger than
DIGIT_BIT. Now returns an error rather than giving wrong result.

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.

result should be MP_YES or MP_NO, not a bare number (1 or 0).

2. Call mp_init() on the k value for the primality test case in the
wolfCrypt test.

ce0136e968 Maintenance: Integers 
In TFM and Integer, rshb() shouldn't try to shift a value that is 0.
This leads to using a negative offset to a pointer, but isn't used.

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.

000fc64f27 Fixes from overnight build failures 
ssl.c: Certificate store fields freed without being NULLed and then
freed again.
integer.c: Compiler complained that a->dp may be NULL in mp_set_bit when
setting bit.
pkcs12.c: ret is zero after GetLength and this is an error but data is
freed only when ret != 0.
pkcs7.c: derArr was not zeroized for full allocated size.
