Cleaned up use of the DEBUG define:

- renamed the DEBUG define for debugging specific code. In the top of
  the relevant files there is an commented out define to activate
  debugging for that file.
- removed entire DEBUG sections where it is no longer relevant
- compile with DEBUG defined when building a debugging binary
Code that produces general warnings is kept in DEBUG blocks.
