Replace "boolean.h" with <stdbool.h>

Be consistent with other programs in base and unify variable usage as
follows to improve readability:

bool = (bool == No) ? Yes : No -> bool = !bool
if (bool == Yes) -> if (bool)
if (bool == No) -> if (!bool)
bool = Maybe -> bool = -1

Allow top to accept tab characters as input in interactive mode
while using the kill and renice commands. This removes a bug
where process numbers that came after a tab character in the
input string would not be affected by the corresponding command.

Fix pointer usage with the renice and kill error message structure. Pointer was used without allocating memory. ok beck@ otto@

Instead of using hand-crafted redraws minimizing screen updates, use curses.
Enables nice things like process highlighting without hurting the brain.

Use sys_signame[] from libc instead of creating a top-specific
signame name to number table. Also use strcasecmp() when matching
signal names for consistency with /bin/kill.

strcat -> strlcat fix. ok tedu@, deraadt@

license change from William LeFebvre <wnl@groupsys.com>; top is now BSD
licensed. this same license will show up on his next release as well.

strlcat

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

kill more registers

First sweep. Prototype, type fixes, long fixes, mostly compiles with
-Wall.

top 3.4, with a few changes. Still needs more work.
