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.

Add revoke(1).

While hacking on TTY code, I often miss a small utility to revoke my own
(pseudo-)terminals. This small utility is just a small wrapper around
the revoke(2) call, so you can destroy your very own login sessions.
