* 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

* Move test support files into tests directory

* Fix common tests dir in test

* Fix Windows Makefile for common tests

* notrandombytes.obj should be in TEST_COMMON_DIR

This way we can properly raise skiptest

* Minor changes

* Gracefully degrade if clang-tidy segfaults

* Typo on returncode

This ensures separate errors for separate common files
