Robert 56db3410c5 MAINT: Update copyright notice to 2021 (Part II)
Apparently the first commit (59ae429972)
did not include all files.

Furthermore the used script tended to produce funny results in certain
cases. This has been fixed and as a result thereof a few more changes
were made in this second run.
