Remove $FreeBSD$: one-line sh pattern

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

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.

Avoid linting GNU contrib'ed stuff, even if the build engineer asked
for it (via WANT_LINT). It's Just Too Noisy.

Makefile.inc was politing all subdir's with SHLIB_{MAJOR,MINOR} definitions.
Since we aren't keeping all the GNU libs at the same versions, this is
useless and causes us to build a shared libgcc, which we don't want to do.

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.

Bump shared-library version numbers.

Add comments to Makefile.inc's about libg++ and shlib nos.

Bump all minor nos. of libs in /usr/src/gnu/lib.
shlibs are now version 1.1

Update for new organization of gnu tree.
