[PATCH 01/40] License Header Clean Up

[Christian Mauderer]

Hello,

during the re-license efforts, Joel noted that there are a lot of really
odd old headers from people at embedded brains. We joined efforts to
clean them up. After this patch series, we should have removed most of
these odd headers.

Please don't hesitate to point out any mistakes that I did during the
clean up. It was a repetitive task and therefore is definitively prone
to errors.

In case some file doesn't reach the list: I also pushed the patches on a
branch on gitlab:

Best regards
