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.

Port lastlogin(8) to utmpx.

While there, fix a bug I introduced previously. We must reopen the
database for each username passed on the command line. We must rewind
the database and search from the beginning.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Port lastlogin(1) to libulog.

Just use ulog_getutxuser() to obtain lastlog records or ulog_getutxent()
to browse through all of them.

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

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Set WARNS=2 on programs that compile cleanly with it; add $FreeBSD$
where necessary.

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

Set the default manual section for usr.sbin/ to 8.

Added the lastlogin utility.
