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.

symlink(7): Mention chflagsat() (can take AT_SYMLINK_NOFOLLOW).

MFC after: 1 week

Add futimens and utimensat system calls.

The core kernel part is patch file utimes.2008.4.diff from
pluknet@FreeBSD.org. I updated the code for API changes, added the manual
page and added compatibility code for old kernels. There is also audit and
Capsicum support.

A new UTIME_* constant might allow setting birthtimes in future.

MFC r207188: symlink(7): The ownership of symlinks is used by the system,
in at least three ways, so do not say it is ignored:
* who may delete/rename a symlink in a sticky directory
* who may do lchflags(2)/lchown(2)/lchmod(2)
* whose inode quota is charged

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.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Reverted some more of rev.1.9 (emphasize that -H != -h).

Revert part of the previous commit. Keep the example that shows how the
"-h" flag is used, but use "chown" in the example instead of "file".

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
