mount_nullfs.8: Bump .Dd for file mounts update.

Add support for mounting single files in nullfs

My main use-case for this is to support mounting config files and secrets
into OCI containers. My current workaround copies the files into the
container which is messy and risks secrets leaking into container images
if the cleanup fails.

Improve description of the nocache option.

Discussed with: pstef

Add nullfs specific nocache option.

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.

$Id$ -> $FreeBSD$

User reports that using mount_null destroyed his filesystem, I reply
that nullfs really doesn't work, he askes why this isn't noted for the
"dangerous" filesystems, I go "hmmm."

-Wall.

Merge from Lite2 (use new getvfsbyname() and mount(2) interface)

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.

delete doubled words, e.g.: "the the" -> "the"

Use the .Bx macro where appropriate.

Fix a bunch of spelling errors.

Fixed a type.
