Remove $FreeBSD$: one-line sh pattern

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

Explicitly add unmarked bin/ binaries to the runtime package.
Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

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.

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

o Remove old code from pwd(1); realpath(1) is now in its own directory.
o Fix some unordered includes in pwd(1).
o Connect realpath(1) to the build.

Default to WARNS=2. Binary builds that cannot handle this must explicitly
set WARNS=0.

MAN[1-9] -> MAN.

Let the pwd program double as realpath(1).

This lets you resolve pathnames to their underlying physical path:

critter# realpath /sys/kern/subr_disk.c
/freebsd/src/sys/kern/subr_disk.c

Update the pwd man-page slightly.

$Id$ -> $FreeBSD$

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.
