NewHope announced a new version of their specification that adds
explicit domain separation. This is a port of

Based on this change:

* 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
