* Integrate Kyber-AVX2 into PQClean

* Fix types and formatting in Kyber

* Workaround a valgrind crash

* Remove comment in shuffle.s

* Remove some extraneous truncations

* fixup! Fix types and formatting in Kyber

* Add support for specifying architecture and feature limits

* cpuinfo not supported on ppc

* Detect 32-bit python interpreter on 64-bit CPU

* Fix bugs in isolated tests

* Also support restricting operating system

* Enable valgrind exit errorcode

It seems we were not doing anything with the valgrind results... D:

* Use --exit-on-first-error if available

* Revert "Merge pull request #182 from PQClean/rainbow"

This reverts commit 8a008417fe988b48c8acc4aefc9c299a4d3c1645, reversing
changes made to d4b612fe9a.

This should drastically reduce the runtime of the valgrind tests

* Do tests with pytest to run them in parallel

* attempt to handle merge commits better for PR test path

Similar to how we solved this for travis

* Clean up imports

* don't run valgrind if not specified slow_test

* Fix functest after initializer rename

* upload tests results as junit

* Upload test-common files since #200 got merged

* Catch test results upload failure

This way we can properly raise skiptest
