$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Correct the .conf files now that halt is gone and reboot is used in it's
place.

Removed mount_pcfs until we have a replacement.

Removed fdisk until it is ported and/or replaced.

Now have to include many more libraries due to /bin/sh changes.

Add proper links so that - and -sh are catered for.

Remove bogus -lcrypt line.

1. Clean the intermediate files when building the default fixit floppy
(demonstration) target.
2. Add the kcopy and filesystem floppy configuration files from Rod.
