HQC submission (#202) * Sebastian's HQC merge request * Clean up changes to common infrastructure * Fix Bitmask macro It assumed that ``unsigned long`` was 64 bit * Remove maxlen from nistseedexpander It's a complicated thing to handle because the value is larger than size_t supports on 32-bit platforms * Initialize buffers to help linter * Add Nistseedexpander test * Resolve UB in gf2x.c Some of the shifts could be larger than WORD_SIZE_BITS, ie. larger than the width of uint64_t. This apparently on Intel gets interpreted as the shift mod 64, but on ARM something else happened. * Fix Windows complaints * rename log, exp which appear to be existing functions on MS * Solve endianness problems * remove all spaces before ';' * Fix duplicate consistency * Fix duplicate consistency * Fix complaints by MSVC about narrowing int * Add nistseedexpander.obj to COMMON_OBJECTS_NOPATH * astyle format util.[ch] * add util.h to makefile * Sort includes in util.h * Fix more Windows MSVC complaints Co-authored-by: Sebastian Verschoor <sebastian@zeroknowledge.me> Co-authored-by: Thom Wiggers <thom@thomwiggers.nl>
