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.

Remove $FreeBSD$: one-line nroff pattern

Remove /^\.\\"\s*\$FreeBSD\$$\n/

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.

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.

- Display current settings when run without options.
- Revise a manpage to NOT sound confusing. [1]

In collaboration with: sat [1]

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

Added the EXIT STATUS section where appropriate.

Remove advertising clause from University of California Regent's license,

Correct a grammatical error.

- Introduce a new struct xvfsconf, the userland version of struct vfsconf.
- Make getvfsbyname() take a struct xvfsconf *.
- Convert several consumers of getvfsbyname() to use struct xvfsconf.
- Correct the getvfsbyname.3 manpage.
- Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the
kernel, and rewrite getvfsbyname() to use this instead of the weird
existing API.
- Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist
sysctl.
- Convert a vfsload() call in nfsiod.c to kldload() and remove the useless
vfsisloadable() and endvfsent() calls.
- Add a warning printf() in vfs_sysctl() to tell people they are using
an old userland.

After these changes, it's possible to modify struct vfsconf without
breaking the binary compatibility. Please note that these changes don't
break this compatibility either.

When bp will have updated mount_smbfs(8) with the patch I sent him, there
will be no more consumers of the {set,get,end}vfsent(), vfsisloadable()
and vfsload() API, and I will promptly delete it.

The .Nm utility

mdoc(7) police: nits.

Turn nfsiod into a vfs loader and sysctl wrapper that controls the number
of nfsiod kernel threads being run.

mdoc(7) police: utilize the new .Ex macro.

Correct cross-reference:
portmap.8 --> rpcbind.8

Submitted by: .Xr testing script

mdoc(7) police: use the new features of the Nm macro.

$Id$ -> $FreeBSD$

Change LKM/modload to KLD/kldload.

Submitted by: Nathan Ahlstrom <nrahlstr@winternet.com>

Correct use of .Nm. Do not dot terminate syslog() strings. Remove unused
#includes. Add rcsid. -Wall.

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.

Use the .Bx macro where appropriate.

Automatically load NFS and a bevy of other filesystems.
