* 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

* 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

* 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

Previously, changing a duplicate_consistency file would be
considered a 'global' change, resulting in CI re-running all tests
for all schemes.

This way we can properly raise skiptest

* Minor changes

* Gracefully degrade if clang-tidy segfaults

* Typo on returncode

* Gracefully degrade if clang-tidy segfaults

* Typo on returncode

use randombytes in functest

Got dropped by the rebase

Work around missing clang-tidy on Travis

Also check if valgrind is available
