Pull Request: https://github.com/freebsd/freebsd-src/pull/1032

Remove $FreeBSD$: one-line nroff pattern

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

A number of places in the source tree still reference cuad.* after
sio(4) was deprecated by uart(4).

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.

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

Sort sections.

Reflect the cuaa->cuad namechange in documentation.

Might as well do them all while I'm at it :-)

Mechanically kill hard sentence breaks.

/etc/rc.serial -> /etc/rc.d/serial.

The .Nm utility

mdoc(7) police: s/BSD/.Bx/ where appropriate.

mdoc(7) police: removed HISTORY info from the .Os call.

Prepare for mdoc(7)NG.

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

Remove the use of a dash in the usage, since this isn't in keeping
with other utilities which offer similar functionality.

This change was discussed with ache, who brought in the ability to
use a dash to represent stdin in comcontrol.

What the commit log for rev 1.16 neglected to mention was that the
delta touched the Name Description (Nd). It introduced a grammar
error and did not fix the extraneous punctuation (Nd lines are not
terminated with a period).

Remove outdated BUGS section. We'll never rename comcontrol to siocontrol.

Print options only supported by device, back out printing options separately

Pointed-by: bde

Allow "-" for working with STDIN
Allow printing of each option separately when keyword specified without a
number

$Id$ -> $FreeBSD$

Add rcsid. Remove unused #includes. Use err(3).

Use .An/.Aq.

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.

Sort cross references.

Minor formatting/style fixes.

Fix even more spelling errors in some more man pages.

rc.local -> rc.serial
cua0? -> cuaa?

Fix punctuation.

From Bde:
o Rewrote lots of it to be more like stty.1. The old one was
too verbose and the complicated options no longer exist.

FILES entry corrected

Change default dtrwait time to 2 seconds.

Man page added.
