Remove $FreeBSD$: one-line sh pattern

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

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.

Mention the path to the README file in the header comment.

Apparently, people do not listen for a plea to look into the
README file before making changes here. Fix them once again.

$Id$ -> $FreeBSD$

Fix script in README to actually work, empty lines produce as
much a diff as lines with the wrong stuff on it.

Add references in mtree data files to the README.

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.

These are mtree generated versions of these files using the
new mtree options.

I will be updating these shortly to remove some old stuff and add some
new stuff. These currently produce the exact same trees as they did.

Add the missing . entries to BSD.*.dist files.

New file BSD.release.dist is used for creating release area top level
directories.
