Allow jail names (not just IDs) to be specified for: cpuset(1), ipfw(8),
sockstat(1), ugidfw(8)
These are the last of the jail-aware userland utilities that didn't work
with names.

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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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

Let bsd.prog.mk set SRCS and MAN to their default values.

Rewrite sockstat(1) in C.

Drop maintainership of this, it serves no purpose.

beforeinstall -> SCRIPTS.

MAN[1-9] -> MAN.

$Id$ -> $FreeBSD$
