mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

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.

Update the manpage for openpty(3) to account for the recent fixes.
Specifically, remove the BUGS section and note that openpty(3) now always
does the various security-related steps. Also, update the error return
value section. The PR below is for the original bug rather than the doc
updates.

$Id$ -> $FreeBSD$

Bad reference of termios(3) changed to termios(4).

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.

Minor mdoc style fixes.

Grammatical changes.

Spelling/mdoc police.

Finally document the interfaces found in libutil. While being here,
also add the missing declaration of forkpty() to libutil.h.

Btw., the calling interface for login(3) is crude. Some better
abstraction is needed, perhaps similar to logwtmp(3).

2.2 candidate, but i'll wait for the spelling police first. :)
