Added the 'const' qualifier to function prototype variables where possible. In addition, reduced some functions to file-scope with 'static' where possible. Also made a few minor changes to remove extra whitespace, and fixed a bug in create_fwknoprc() to ensure the new fwknoprc filehandle is closed.
