Remove unneeded functions from libcompat.

Erwin fired up a ports build a couple of weeks ago and it seems the
following functions are not used by any of the 20k ports we have, which
makes me believe they don't have any purpose. Just remove them.

Trim down libcompat by removing <regexp.h>.

Erwin ran an exp-run with libcompat and <regexp.h> removed. It turns out
the regexp library is almost entirely unused. In fact, it looks like it
is sometimes used by accident. Because these function names clash with
libc's <regex.h>, some application use both <regex.h> and libcompat,
which means they link against the wrong regex library.

This commit removes the regexp library and reimplements re_comp() and
re_exec() using <regex.h>. It seems the grammar of the regular
expressions accepted by these functions is similar to POSIX EREs.

After this commit, 1 low-profile port will be broken, but the maintainer
already has a patch for it sitting in his mailbox.

Small style(9) cleanups.

K&R -> ANSI

Add a missing parameter to ruserpass(). According to C99 6.9.1p7
K&R function is not a prototype but this is a bad style. GCC accepts
this other compilers warn or reject this.

Remove California Regent's clause 3, per letter

Mechanically kill hard sentence breaks.

Consistently mark std(in|out|err) with .Dv, because that's how they
are marked up in stdio(3), and because they are defined expressions
of type "FILE *".

- Remove the lsearch() and lfind() functions and their manpage from
the compatibility library libcompat.
- Add new implementations of lsearch() and lfind() which conform to
IEEE Std 1003.1-2001 to libc. Add a new manual page for them and
add them to the makefile.
- Add function prototypes for lsearch() and lfind() to the search.h
header.

- Remove the old insque() and remque() functions and their manual
page from the compatibility library.
- Add new implementations of insque() and remque() which conform to
IEEE Std 1003.1-2001 to libc. Add a new manual page for them and
connect them to the build.
- Add the prototypes of insque() and remque() to the search.h
header.

Remove 'register' keyword.

Prepare for mdoc(7)NG.

Remove text saying "this is available from the compatibility library,
libcompat" in favour of a .Sh LIBRARY section using the .Lb macro. Also add
.Bf -symbolic around the text saying "this is obsolete" in re_comp.3.

Remove fullstops from the end of .Xr lines in SEE ALSO section.

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

Return an error instead of overflowing the buffer in the case of a long
$HOME in ruserpass()

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

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.

Add a short man page for cfree(3), in order to hint people about its life in libcompat.

Remove trailing whitespace.

The implementation of rexec() missed the function ruserpass(), so the
link stage fell over for any program that attempted to use rexec().

Ruserpass() remains undocumented; i could not find any documentation
for it on other systems.

Also added a BUGS section to the man page, stating that this function
constitutes a potential security hole (as well as the underlying
"exec" service).

My libcompat cleanup.

o add missing man pages

o make all man pages clearly refer to the libcompat thingie

o add the information to the vtimes(3) and vlimit(3) man pages
that nobody has reimplemented the functions by now

o add the missing getpw.c

o add code and man pages for cftime(3) and
ascftime(3) -- i found them somewhere in old
unfinished work

add a couple of missing #include lines

Add sanity check for "no previous regular expression" state,
bringed by 'more'

Fix bug with searching "" pattern, cause 'more' always shows
next line on "/<Enter>" instead of searching next pattern
