Add StringWiden function
StringWiden converts a narrow C-style string to a wide string. It serves the opposite role of StringNarrow function. The function is useful on Windows platforms where the OS favors wide functions with the UTF-16 character set. For example, the Data Proction API (DPAPI) allows a description, but its a wide character C-string. There is no narrwo version of the API.

Add MOVBE support
MOVBE is a modest gain over BSWAP. Though its guarded by CRYPTOPP_MOVBE_AVAILABLE, we cannot detect availability with a preprocessor macro. That is, GCC does not provide __MOVBE__ or similar. It has to be enabled manually

6bfa0d9ab0 Cleared Coverity finding CID 170383 (INTEGER_OVERFLOW) (295)
ModPowerOf2 was changed to include a saturating subtract. Unintuitively, the code got faster rather than slower. The saturating operation appears to have helped the optimizer

This avoids a circular dependency between misc.h and trap.h. It also allows us to logically segregate and group code to replace C++ handlers, like set_terminate

__BIGGEST_ALIGNMENT__ is provided by some compilers, like GCC and ICC (but not Clang). It is usually 16 on 64-bit platforms; and it is usually 8 on 32-bit platforms
