Add static keywords to variables and functions where possible in games/.

This allows us to detect unused functions and variables and allows the
compiler to do a better job at optimisation.

Drop advertising clause in manpages. It was done a long time ago
for the source code.

Discussed with: core

Remove the third clause for the Berkeley parts of games, per the
letter in /COPYRIGHT.

games: make WARNS=6 the default, remove overrides

This also bumps factor, fortune, primes, and random to WARNS=6.

Approved by: ed (Co-mentor)

Use ANSI C function declarations.

Make number(6) build with WARNS=6.

Expand *n't contractions.

Sync program's usage() with manpage's SYNOPSIS.

Fixed a mispelling of 0 as NULL.

Remove __P
Remove __STDC__ (which means we now use stdarg rather than vararg)
Remove register
Remove main prototype

- Backout botched attempt to intoduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for games/ to 6.

mdoc(7) police: use the new features of the Nm macro.

mdoc(7) police: Nm is a must in the NAME section.

-Wall fixes.

copyright/sccsid/rcsid cleanup.

Fix breakage by previous commit.

Sync our register usage with NetBSD's (non-)usage.

Add $FreeBSD$

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Wargh! Who went and changed all the getopt() comparisons from -1 to
EOF? The getopt(3) manpage clearly states that the return value is *-1*,
not EOF! Besides, getopt(3) isn't reading from a file. :)

Noticed-while: merging to 2.2 (where this is correct).

Fix a core dump caused by negative numbers.
