Branch: MAIN

This diff is rather large, but it's just simply removing unnecessary headers
, remove some lint-style comments, add missing void to functions without args,
also some function prototypes (extern) were missing their args, so I added them
as they were defined in hack.h
OK tb@ on separate diffs
