Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Pull Request: https://github.com/freebsd/freebsd/pull/96

Add two new system calls, setloginclass(2) and getloginclass(2). This makes
it possible for the kernel to track login class the process is assigned to,
which is required for RCTL. This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

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.

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

Add a -a option as a no-op for Solaris compatibility, as briefly
discussed on src-committers. This is intentionally not included in the
usage() function as it would confuse the output too much.

Rename "-a" flag to "-A" in order to avoid conflicting with the "-a" flag

Added the EXIT STATUS section where appropriate.

Bump document date on behalf of the -M option.

Add "-M" argument to id(1), which permits the id command to be used
to print the MAC label of the current process. "-M" selected as that's
what is used in Trusted IRIX.
