Remove $FreeBSD$: one-line sh pattern

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

Spelling fixes for tools/

Add some $FreeBSD$ tags so svn will allow the commit.

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.

Remove the uarea column from the DDB 'ps' display, and from grog's gdb
scripts.

Remove calls to 'y' macro.

Make btpp and fr work. There's still more to be done.

Add macros for kernel debugging. These have been around for a
while, and they will need some more tuning before they're really
useful, but at the moment they're better than nothing.
