log
@Fix legacy C. Pass -Wall -W -Wmissing-declarations -Wwrite-strings on
gcc45.

   - avoid implicit int, declare void functions void
   - return values from non-void functions
   - put most external declarations properly in header files
   - use some static and const
   - fix up a big mess with function pointer casting
   - use standard includes, don't provide own decls of standard functions
   - use types matching libc when providing own malloc, printf, and putchar
   - use <ctype.h> functions correctly
   - silence assorted compiler warnings
   - fix some bugs exposed by compiler warnings
   - don't intentionally exercise signed overflow
   - remove some unused items
   - add patch comments to other patch (patch-aa)

As this includes several fixes and removes some undefined behavior on
a commonly reachable code path, bump PKGREVISION.

@$NetBSD$

- use const for string constants
- declare void functions void
- remove stray extra copies of function declarations from elsewhere
