What needs to change is the license header in the various files.

I'm not the copyright holder of the sources in question, so it's not
appropriate for me to provide a patch that changes the license.

Using GPL-2+ for all files in mgkmap & splitter would be best, as that
also solves the issue when GPL-4 is introduced.
