MFC r250982: sigreturn(2): Remove ancient compatibility warning about 4.2BSD

The HISTORY subsection still says that sigreturn() was added in 4.3BSD.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Update xrefs from 4.3BSD to modern signal functions in various man pages.

sigvec(2) references have been updated to sigaction(2), sigsetmask(2) and
sigblock(2) to sigprocmask(2), sigpause(2) to sigsuspend(2).

Some legacy man pages still refer to them, that is OK.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Fix prototype.

mdoc(7) police: "The .Fa argument.".

mdoc(7) police: Tidy up the syscall language.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.

Update to reflect reality.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Update to reflect current include files.

Correctly use .Fn instead of .Nm to reference function names
in a bunch of man pages.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
