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 NO_WERRORs and WARNS=n's. To be revisited after GCC3.

WARNS=2 fixes with NO_WERROR set because of system-header originating

$Id$ -> $FreeBSD$

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.

Make talk automagically find out the interface IP address where the
remote peer will be connected through. This avoids the ``Checking for
invitation on caller's machine'' problem for multi-homed hosts.

Thanks to: Garrett, for his `find_interface' example

Not sure why this one was -lcompat since it doesn't reference anything in
it.

Change all references to LIBTERM and -ltermlib to LIBTERMCAP and -ltermcap
