wants to do a full zfs machine.

Only set WARNS if not defined

This would allow interested parties to do experimental runs with an
environment set appropriately to raise all the warnings throughout the
build; e.g. env WARNS=6 NO_WERROR=yes buildworld.

Not currently touching the numerous instances in ^/tools.

Convert sbin/ to LIBADD
Reduce overlinking

A new jail(8) with a configuration file, to replace the work currently done

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.

Raise WARNS for various tools where possible.

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

Added UFS library to the bsd.libnames.mk namespace.

Make tunefs use libufs, it seems to do well enough for printing / setting
things.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for sbin/ to 8.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
