Make the default WARNS for games 4. The only game that needs to set WARNS
to anything else now is rogue, so clear WARNS from the other makefiles.

Xref shuffle(1) from random(6), and vice versa

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

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

Lots of minor fixes resulting from reading these man pages in detail.

More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Many more to
come.

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

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

Define and use MAXRANDOM instead of LONG_MAX.

Add `__noreturn__' and `__unused__' attributes where appropriate to
the games.

This merges in all such remaining changes from the Linux port of the
NetBSD games, except in hunt (where substantial changes from OpenBSD
need to be looked at).

Most noreturn attributes were previously added in bin/6144, with some
others that were missed then in bin/8082. Previous `unused'
attributes were covered in bin/6557, bin/8058 and other PRs (all these
PRs have already been handled and closed).
