Remove $FreeBSD$: one-line sh pattern

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

Convert to usr.bin/ to LIBADD
Reduce overlinking

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

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.

Add libjail, a (somewhat) simpler interface to the jail_set and jail_get
system calls and the security.jail.param sysctls.

- Import the HEAD csup code which is the basis for the cvsmode work.

After positive feedback from a few folks, activate a switchover to
using killall.c instead of the perl version that depends on procfs.
The C version uses sysctl(). The program is based on a hack that was
originally written about 6 years ago and has evolved somewhat since then.
(which is why it is a superset of killall.pl, rather than being a clone.)

With apologies to: wosch

$Id$ -> $FreeBSD$

Added myself as maintainer.

Our Perl oracle hit again: Wolfram Schneider's killall utility.
Kills processes by name instead of by UID.

(Man page by me.)
