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.
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.
These header files only provide functionality that can be used in
combination with libcompat. In order to prevent people from including
them without any actual use (which happens a lot with <sys/timeb.h>),
put a warning here to make people more aware.
This means we have to lower WARNS for libcompat, which is no big deal.
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.
I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.
sgtty was the original interface to configure terminal attributes on my
UNIX-like operating systems. It has been deprecated by the POSIX termios
interface, which is implemented in almost any modern system.
An advantage of turning this into a binary compatibility interface, is
that we can now eventually remove the COMPAT_43TTY switch from kernel
configurations. This removes many ioctl()'s from the TTY layer.
While there, increase the __FreeBSD_version, which may be useful for the
people working on the Ports tree.

- 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

this makefile update which should have been together with the file
removal.
Removed vlimit.3 and vtimes.3. Removed vlimit.c and vtimes.c from
the "MISSING" list. These were old variants of get/setrlimit() and
getrusage(), respectively, and were never implemented in FreeBSD.
vlimit.3 referred to <sys/vlimit.h> which was removed recently.
vtimes.3 referred to <sys/vtimes.h> which never existed in FreeBSD.
Also corrected a few minor formatting errors, file location and cross
references in some of the section 3 man pages.
This shuts up a lot of the output from "manck" for section 3.
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
Since functions will come and go from libcompat as they are deprecated
it makes no sense to build a shared library out of it as it will change.
Based on freedback from Terry and Jonas on the mailing lists.
