rain(6): Update the "rainable area" upon SIGWINCH

This makes sure rain falls to fill the entire window even if the window
grows in size.

rain(6): Avoid division by zero

If there were exactly 4 LINES or COLS then we'd attempt to draw a raindrop
at some value mod 0, which is invalid.

rain(6): Make the default delay useful for modern terminals

Sync with wrstuden-revivesa-base-2.

if initscr() fails, exit with a message rather than crash in the
next curses call

Remove the \n and tabs from the __COPYRIGHT() strings.

sync with HEAD

convert __attribute__s to applicable cdefs.h macros

Enable WARNS=3 and pass lint(1).

ok christos@

- don't catch STOP, TSTP, QUIT; the first you cannot catch and the other two
  you should not.
- don't accept delay == 1000, because it turns to 0 and fix the number parsing
- misc KNF cleanups.

Hide the cursor if possible.  From OpenBSD.

Remove uses of __P.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22269, verified by myself.

Revert inclusion of <string.h> now that curses has been fixed.

Need <strings.h>.

This patch converts rain(6) to use curses, thereby
significantly simplifying the code and improving its portability.  It
also adds a delay option from OpenBSD to make the display go at a
useful speed on fast terminals, and fixes signal handling to make it
reliable.

Patch supplied by Joseph Myers <jsm28@cam.ac.uk> in PR 6659.

#include <string.h>

use <termcap.h> instead of <curses.h> for termcap(3) functions

WARNSify

Use POSIX tty semantics.

clean up fputchar types (again)

clean up import.  NetBSD RCS IDs

src/games/rain from Lite

TIOCGWINSZ

Eliminate a compiler warning.

Add RCS identifiers.
