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.

Move msg{snd,recv,get,ctl} manual pages from section 3 to 2.

Approved by: re (kib)

Mechanically kill hard sentence breaks.

The ftok() function has not been in libcompat for quite a while.

mdoc(7) police: Use the new .In macro for #include statements.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

$Id$ -> $FreeBSD$

Various man page cleanup:

- Sort xrefs
- FreeBSD.ORG -> FreeBSD.org
- Be consistent with section names as outlines in mdoc(7)
- Other misc mdoc cleanup.

This is a null commit to log the fact that I have done a repository
copy to bring these files into libc from libcompat. I will enable
them and kill off the libcompat versions on the main branch soon.

PR: step one toward closing misc/6763

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq

FIxed arg types (mostly missing consts) in synopsis.

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"

Minor corrections. The second parameter is actually of type int
(though only char will be used), and our implementation is not really
worse than the SysV one, so there's no need to claim so in the BUGS
section.

Correct the xref for msgctl: msgctl(2) -> msgctl(3)

Another round of spelling fixes.

Added function and man page for ftok(3), used in conjunction with
the so-called "System V IPC".
