Clarify licenses

2018-11-08T17:18:20+00:00

- add license headers to everything
- convert a few files from public domain or LGPL2.1+ to GPL2+
- some archaeology to clarify which files are from which library

Header cleanup: stop using Glib types where they aren't truly needed. Eases GThread deprecation errors.
