rup: Fix -Wcast-align warnings

Fix possible strict aliasing issue (if time_t is the same size as int but
not int but for example long) which also resulted in a false positive
warning on systems with 64-bit time_t. Pointer casts are bad; we can just
copy the time_t.

Elsewhere, avoid casting char * to int * by using memcpy().

rup: compile with WARNS=6

Bump level WARNINGS to 3

Convert to usr.bin/ to LIBADD
Reduce overlinking

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.

MAN[1-9] -> MAN.

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
