NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future 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.

Always assign WARNS using ?=

- fix some nearby style bugs
- include Makefile.inc where it makes sense and reduces duplication

- Import the HEAD csup code which is the basis for the cvsmode work.

Style: NO_MAN doesn't need any value.

Add a simple KVM tool to dump the kernel state of UMA, including walking
the keg/zone lists, summarizing cache state, and walking bucket lists in
each zone. I seem to get inconsistent results on SMP, possibly due to
local header problems, but it seems to work quite well on UP. This tool
requires sufficient privilege to read /dev/mem (or a core dump), and is
for debugging purposes rather than administrative monitoring purposes
(use vmstat instead).
