more precise copyright

- upstream shifted to LGPL for many files (some still GPL)
- some copyright attribution removed due to files being removed
- fix typos in copyright names ("Textronix")
- some documentation files are GFDL
- clarify that only files under debian/ have been edited by maintainer
  (changelog is still ambiguous)
- update FSF copyright year range for some recent changes
- turtle file was removed
- configure file is covered
