* Fix a bunch of issues in SPHINCS+ on Windows
* Fix testing makefile dependencies by fixing times of common files
  (affected Windows testing mainly)

NIST announced the Round 3 finalists and alternate candidates today:

Some of the schemes in PQClean did not make it to Round 3 and this commit
removes them.

* Add AVX2 version of mqdss

* Fix duplicate consistency

* don't do filesystem operations during collection

* Greatly speed up test collection

* fixup! Greatly speed up test collection

* Silence junit warning

* fixup! Greatly speed up test collection

* 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

* Put AES ctx on the heap

This forces people to use the ``ctx_release`` functions, because otherwise there will be leaks

* Put fips202 on the heap

* Add much more docs for fips202.h

* fixup! Put fips202 on the heap

* Put SHA2 on the heap-supporting API

* Fix clang-tidy warnings

* Fix unreachable free() in falcon

* Fix McEliece8192128f-sse GNU Makefile

* Add McEliece reference implementations

* Add Vec implementations of McEliece

* Add sse implementations

* Add AVX2 implementations

* Get rid of stuff not supported by Mac ABI

* restrict to two cores

* Ditch .data files

* Remove .hidden from all .S files

* speed up duplicate consistency tests by batching

* make cpuinfo more robust

* Hope to stabilize macos cpuinfo without ccache

* Revert "Hope to stabilize macos cpuinfo without ccache"

This reverts commit 6129c3cabe.

* Just hardcode what's available at travis

* Fixed-size types in api.h

* namespace all header files in mceliece

* Ditch operations.h

* Get rid of static inline functions

* fixup! Ditch operations.h

Having the keys on the stack increases the stack space consumption by
quite a bit, and this in turn results in the sanitizer tests failing
for Rainbow.

Moving the keys to the heap in the test seems like a harmless change.

* Add state destroy to SHA2 API

* Include optimized SPHINCS+ implementations

I've generated new implementations from the sphincsplus repository.

* Don't destroy sha256ctx after finalize

* Attempt to shut up MSVC

* Make sure to drop errors in rmtree

Every .s file is now handled through CC

* Copied qTESLA-p-I round2 (2019-08-19) code

* Code compiles, NIST-KAT works

* Included detached signature API

* Generated testvectors

* Fixed name in api.h

* code style

* Fixed error in Makefile

* Passing pytest

* Fixing types (uint8_t bytes and size_t indices)

* Replaced SHAKE with SHAKE128 where necessary

* Fixed bug: (signed) integer overflow

* Added qTESLA-p-III

* Code is now independent of machine endianness

* repaired Microsoft makefile

Add duplicate consistency files
