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

Match bwrite()'s prototype with write()'s, zapping a lint comment
Delete casts to char* of arguments to bwrite() and free()

lint is dead (long live the lint!)

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

De-register, ANSIfy, clean up.

hack is free

Thanks to Andries Brouwer, Jay Fenlason and the folks at CWI for their
