Remove code for CITRUS!=yes.

Fixes PR lib/39662, shortcomings in LC_{MONETARY,NUMERIC,TIME,MESSAGES} db format.
ok'ed by core and releng.
(thanks for agc@, snj@ and i'm sorry for long time patience).

[libc]
- localeio.[ch] and lc*.[ch] in src/lib/libc/locale was replaced by
new locale-db implementation using citrus_db backend,
see src/lib/libc/citrus/citrus_lc_*.[ch].
- add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation
internally, because they're locale-aware function.
- add some stubs for multi-locale issue, see {current,global}_locale.c.
- remove some obsolete file, setrunelocale.c, ___runetype_mb.c.
- remove __savectype() from ctypeio.[ch].

[tools]
- mklocale(1): add new option ``-t'' that generates new style
LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format.
- chrtbl(1): added ctypeio.[ch] for __savectype().

[locale-db]
- added en_US.US-ASCII locale.
- removed some shareable locale definition file:
en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8
zh_CN.eucCN -> zh_CN.GB18030
and more...see src/share/locale/*/Makefile.
- remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS.
- change locale name ja_JP.ISO2022-JP* -> ja_JP.ISO-2022-JP*
for X11's locale.alias file alignments.
- fix regression test, wrong wcs?width(3), NAN/INF usage.

i tested release-build following arch:
i386, amd64, hpc{mips,arm,sh}, sparc64, vax.

citrus_lc_*.[ch] also can read old-plain-text style locale-db.
so that backward compatibility is keeped, but lc*.[ch] can't read
new citrus_db'ed locale-db and localeio.c never check sanity,
so forward compatibility is broken ;-<

old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.

add iconv.3 manpage.

Citrus iconv support(4)
add iconv external I/F (iconv.h - iconv_open()/iconv()/iconv_close()) and
iconv(1) utility.
TODO:
- bump libc minor.
- add iconv data files.
- create manpages: iconv_open(3)/iconv(3)/iconv_close(3)/iconv(1)/
mkesdb(1)/mkcsmapper(1).

Switch the iconv(3) prototype to the POSIX conformant variation

Remove const from the 2nd argument.

const char ** and char ** are incompatible types and it was a cost to keep
the technically incompatible form for a more purist variation. NetBSD was
almost the last alive OS to still keep the const argument (known leftovers:
Minix and Illumos).

Keep the const form for the internal purposes inside citrus and rump.

Address the build breakage fallout in the same change.

There are no ABI changes.

Change accepted by core@.

Bump date for previous.

Sync STANDARDS of iconv(3) with current reality

GNU libiconv is no longer incompatible with POSIX since 2007.

Solaris 11 moved to POSIX.
Illumos moved to POSIX http://illumos.org/man/3c/iconv

New software is aligned to POSIX not to the old mistake in the standard.

conforms -> conform, since it's the verb for three nouns and thus plural.

s/conform/conforms/1

fix rev.1.13

Remove trailing whitespace.

Rework the description of the const issue to improve the wording,
avoid saying "we", fix typos, etc.

XXX: groff and mandoc handle the URLs in here differently but both
XXX: mangle them, apparently because they're wider than one line.
XXX: Does anyone know how to fix this or do we need an URL shortener
XXX: on www.NetBSD.org?

Use Lk for links.

Explain why we did not follow the standard.
Worth revisiting the proposal:

Sort errors.

Properly enumerate the two special cases. Also some markup improvements.

revert the last all changes related to iconv(3).

Bump date for previous.

sync with the current iconv() prototype.

Misc fixes from jmc@openbsd.

Mark up NULL; bump date for last; drop trailing space.

fix the problem about resetting the state of iconv().
iconv() was not conforming to the SUSv3 at this point.
reported by Bruno Haible.

Sprinkle some restrict, repair a minor nit in iconv(3)'s synopsis.

Grammar improvement.

correct a careless miss.
add the mention about the buffer size when resetting destination state.

Improve wording.

Grammar, punctuation, and mdoc fixes. Sort sections.

add iconv.3 manpage.

Revert to revision 1.8. Blindly ignoring options is not acceptable
behavior and hides more problems than it is fixing.

Discussion:
http://mail-index.netbsd.org/current-users/2009/02/03/msg007761.html

Approved by: core@

a better method to truncate at // marks

Check for NULL return from strdup()

Ignore the magic // commands in iconv_open(). This was discussed on current-users about a month ago, and ignoring the options was the best suggestion.
