usr.bin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Fix libxo output from uptime command

the libxo output for uptime returned multiple 'uptime' keys, one each for number of days, hours, and minutes of uptime.
This is invalid JSON.
This patch makes the output the raw number of seconds, as well as adding keys for the individual unit values
A string of the original output from the plain-text uptime command is also added

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 w(1) to utmpx.

Let it print "-" when the TTY string is empty. In this case, it must
also make sure it doesn't match processes who also have no controlling
TTY. Otherwise it will print random kernel processes when trying to pick
the best matching process.

Eventually it should look at the value of ut_pid as well.

This now passes a make universe with WARNS=6.

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

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

Let w(1) use utmpx.

We don't have UT_*SIZE anymore. One of the reasons for that is because
all strings are null terminated, there is no need for apps to copy
strings out of the utmpx structure. This means we can define W_DISP*SIZE
lengths for all columns.

While there, adjust the sizes a little. Steal some bytes from the
username column, while extending the hostname column quite a bit.

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

When -n is specified, don't attempt to turn hostnames found in utmp
into addresses as we have no idea what address family they belong to.

When -n is not specified, resolve IPv6 as well as IPv4 addresses found
in the host field of utmp. Use realhostname_sa() to resolve addresses
(the old code was wrong).

Rename ``x'' to ``x_suffix'' to avoid confusion.

Hard code the host column width to 16 (against the imminent increase
of UT_HOSTSIZE in utmp.h).

MAN[1-9] -> MAN.

Use the same technique as ps(1) to avoid the need for setgid. (ie: use
/dev/null as the default kernel and /dev/mem filenames, but still allow
the usual overrides)

Install with default BINOWN (as it once used to be).

Install setgid kmem rather than setuid root. The problem with procfs that
was breaking this before has been fixed.

Make it set-uid until procfs is fixed.

More merry makefile munging for man page compatability.
