Merge remote-tracking branch 'remotes/huth-gitlab/tags/pull-request-2019-05-09' into staging

- Fix "make check" problem that occurred with LANG=C and Python 3.5 / 3.6
- Get rid of some more dependencies on the global_qtest variable in the qtests
- Some other small test clean-ups
- Some copyright statement clarifications
- Mark TARGET_FMT_lu as poisoned
