crunch: Sync some NetBSD changes.

crunchide:
Apr 11, 2009: fix some -Wsign-compare issues.
Sep 20, 1999: Free the right thing.

crunchgen:
Apr 14, 2009: Fix some WARNS=4 issues (-Wshadow -Wcast-qual)
Oct 30, 2004: Add (unsigned char) cast to ctype functions
Feb 5, 2001: fix nested extern.

examples:
Aug 30, 2007: NetBSD 36867 - trsp references are deprecated

In order to merge this I also had to merge some previous changes:
- Ensure crunchen uses the same make binary as the rest of the
build.
- Some amount of style(9): function definitions, header ordering,
and $FreeBSD$.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Remove extra space introduced by the previous commit.

Remove pppd and SLIP-related stuff.

Remove reference to mount_fdescfs.

Reminded by: ru

Push removal of mrouted down to the rest of the tree.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

mount_msdos(8) -> mount_msdosfs(8).

mount_fdesc -> mount_fdescfs
mount_portal -> mount_portalfs

Retire kernfs (userland part).

$Id$ -> $FreeBSD$

Add a new special called `keep' to the list of special options. It
provides for a means to specify an argument for crunchide's -k option.
(This is required by ntpdate.)

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.

Need /usr/src/sbin/i386 in srcdirs to get fdisk.

Could you please commit this patch to usr.sbin/crunch/examples ?
This should make fixit.conf compilable again.
VI needs some hacks.

[Note: I'm not sure how relevant this example is anymore, but then it's only
an example]

-lcompat removed from libs

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.

John Capo's changes to make the fixit floppy image work; I didn't even
bother looking at this file before! :)

Whoops, missed the .cache files - those can be tossed too.

Nuke all the intermediate files.

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