Sort sections.

Add or correct section number in .Xr. Use .Vt or .Fn
instead of .Xr when needed

popen() is a function, not an argument.

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

mdoc(7) police: use certified section headers wherever possible.

Avoid use of direct troff requests in mdoc(7) manual pages.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

$Id$ -> $FreeBSD$

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.

Fix a .Nm -> .Fn fix that was missed in the previous commit.

Pointed-out-by: Bruce Evans

Update manual page to reflect changes in rev 1.12 of
"src/lib/libc/gen/popen.c" --- popen() in the child
now closes any copies of popen()'ed descriptors in the parent.

Mention when bidirectional features first appeared.

Document that popen() uses a bidirectional pipe (in FreeBSD) and not a
socket pair (as in Lite2).

Merge from Lite2 (YAMFL2? :-)
Document that popen() can now create bidirectional pipes and handles.
Note that this needs to be updated since we have a native bidirectional
pipe and don't use socketpair() here.

Sort cross references.

Added missing section numbers to a bunch of .Xr macros, or
converted them into .Fn macros where appropriate. Also fixed
up some minor formatting problems.
