usr.sbin: 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.

Convert usr.sbin 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.

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

- Make pstat(8) WARNS=6 safe.
- While here, eliminate the check for len > 0 in ttymode_sysctl
as the code is able to handle this case well.

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

Use a designator for initializing only one member of the nlist
structs, making pstat WARNS=3 clean on i386, sparc64 and amd64.

Bump WARNS level to 3.

- Add a -h flag to pstat to print swap sizes in "human readable"
format, with humanize_number(3).

- Move the common parts of the code that prints the sizes for a single
swap device and the total to a single function to avoid repeating
the humanize_number() stuff all over the place.

- Change the type of CONVERT() from intmax_t to int64_t, since this
makes calling humanize_number() easier but cast the values to
intmax_t before printing them, to make use of the %jd format that
printf() supports.

- Document the new -h flag in the manpage and bump its date.

style.Makefile(5)

Remove the code that was disabled in a recent commit; it is of very limited
use and has been broken in -CURRENT for a long time.
Clean up unneeded entries in the nlist array.
Implement kvm-backed ttymode (which we never had before). Incomplete as we
do not (yet?) print the correct device, sid or pgid.

Un-kmemize. Portions of the tty mode code have been temporarily disabled;
everything else, including dead kernel support, works just like before.

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.

- FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file
systems were repo-copied from sys/miscfs to sys/fs.

- Renamed the following file systems and their modules:
fdesc -> fdescfs, portal -> portalfs, union -> unionfs.

- Renamed corresponding kernel options:
FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.

- Install header files for the above file systems.

- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland
Makefiles.

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

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

Previous commit to remove -I/sys broke 'make world', miscfs/union/*.h is
not (yet?) installed in /usr/include.

Remove -I/sys

Make pstat act like swapinfo if so invoked.

Get rid of update. Make man page installation work with our scheme
(and rename a few in the process).
