GLUT: Relicense Mark Kilgard's GLUT components

* A copy of the email approving this change is
  in the LICENSE.txt file
* This clears up several concerns
* We now have permission to clean / update GLUT
  code and redistrubute its binaries.
* We have to ensure all of Mark's work is *not*
  GPL licensed as per his wishes.
