The tow* functions use an included case conversion table which can be
generated from Unicode data.
The isw* functions use a character categories table (provided by
categories.c) which can be generated from Unicode data.
Delegation between current-locale and specific-locale-dependent functions
was reverted towards the generic locale-dependent functions (*_l.c);
this is however only relevant on systems with non-Unicode wide character
locales, thus not on Cygwin.

_MB_CAPABLE systems.

* libc/ctype/jp2uc.c (__jp2uc): On Cygwin, just return c.
Explain why.
* libc/ctype/towlower.c: Ditto.
* libc/ctype/towupper.c: Ditto.
* libc/include/sys/config.h: Define _MB_EXTENDED_CHARSETS_ISO
and _MB_EXTENDED_CHARSETS_WINDOWS if _MB_EXTENDED_CHARSETS_ALL is
defined. Define _MB_EXTENDED_CHARSETS_ALL on Cygwin only for now.
* libc/include/sys/reent.h (struct _reent): Mark _current_category
and _current_locale as unused.
* libc/locale/locale.c: Add new charset support to documentation.
Include ../stdio/local.h from here.
(lc_ctype_charset): Set to "ASCII" by default.
(lc_message_charset): Ditto.
(_setlocale_r): Don't set _current_category and _current_locale.
(loadlocale): Add Cygwin codepage support. On _MB_CAPABLE
systems, set __mbtowc and __wctomb function pointers to function
corresponding with current charset. Don't allow non-existant
ISO-8859-12 charset. Add support for Windows singlebyte codepages.
On Cygwin, add support for GBK, CP949, and BIG5. On Cygwin,
call __set_ctype() in case the catorgy is LC_CTYPE. Don't set
_current_category and _current_locale.
* libc/stdlib/Makefile.am (GENERAL_SOURCES): Add sb_charsets.c.
* libc/stdlib/Makefile.in: Regenerate.

Add prototypes for __mbtowc and __wctomb pointers.
Add prototypes for charset-specific _wctomb_r and _mbtowc_r
functions.
Declare tables and functions from sb_charsets.c.
* libc/stdlib/mbtowc_r.c (__mbtowc): Define. Set to __ascii_mbtowc
by default.
(_mbtowc_r): Just call __mbtowc from here.
(__ascii_mbtowc): New function.
(__iso_mbtowc): New function.
(__cp_mbtowc): New function.
(__utf8_mbtowc): New function.
(__sjis_mbtowc): New function. Disable on Cygwin.
(__eucjp_mbtowc): New function. Disable on Cygwin.
(__jis_mbtowc): New function. Disable on Cygwin.

conversion tables for all ISO and CP charsets.
(__iso_8859_index): New function.
(__cp_index): New function.
* libc/stdlib/wctomb_r.c (__wctomb): Define. Set to __ascii_wctomb
by default.
(_wctomb_r): Just call __wctomb from here.
(__ascii_wctomb): New function.
(__utf8_wctomb): New function.
(__sjis_wctomb): New function. Disable on Cygwin.
(__eucjp_wctomb): New function. Disable on Cygwin.
