crunch: remove fdisk from examples

It has been deprecated for a long time; gpart should be used instead.
The man page was updated in 2015 to declare it obsolete (b8c19fd719945).

Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

send-pr: wave goodbye

Entering into the world of 12.x we no longer need even the placeholder
for send-pr. It has not done anything for some time.

Remove badsect(8).

Failure modes of the modern (that is, produced in the last 25 years)
hard drives and SSDs made the utility outdated. Since the kernel
interface to support it was removed in r324853, cut the userspace
remnants as well.

Discussed with: bde (who does not like the removal)

Deorbit catman. The tradeoff of disk for performance has long since tipped
in favor of just rendering the manpage instead of relying on pre-formatted
catpages. Note, this does not impede the ability to use existing catpages,
it just removes the utility to generate them.

Disconnect non-MPSAFE PORTALFS from the build in preparation for dropping
GIANT from VFS.

This is not targeted for MFC.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

MFC r201211:

Remove pppd and SLIP-related stuff.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Remove extra space introduced by the previous commit.

Retire kernfs (userland part).

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.)

This is the new crunch utility for making distribution floppies from
James da Silva. We need to integrate this before 1.1.5 so that we can
actually make the boot floppies.
