I (force) pushed an updated version of wip/cffi (8d1f30cb) with several changes
along those lines to the configure / build / test scaffolding. In
particular running the tests from the notmuch suite doesn't require
pytest-cov anymore, and pytest and cffi are both checked for only if
python3 is found.
