difference between eucJP and CP 20932 affecting JIS-X-0212 characters.
Explain.

in call to MultiByteToWideChar. Fix a problem with singlebyte
sequences. Fix a bug in '\0' handling. Reset state->__count on
successful return from non-zero state.
(__jis_mbtowc): Just call __ascii_mbtowc from here.
(__eucjp_mbtowc): Convert to standalone implementation to fix up the
difference between eucJP and CP 20932 affecting JIS-X-0212 characters.

(__set_charset_from_codepage): Handle codepage 20932 as eucJP.
ctype_cp.h out of ALLOW_NEGATIVE_CTYPE_INDEX case.
(__ctype_ptr__): Constify in !_MB_CAPABLE case. Otherwise,
de-constify in !ALLOW_NEGATIVE_CTYPE_INDEX case, too. Add comment.

of ALLOW_NEGATIVE_CTYPE_INDEX.
* libc/include/ctype.h (__ctype_ptr__): Constify in !_MB_CAPABLE case.
(fixup_shms_after_fork): Fix comment. Use NtMapViewOfSection rather
than MapViewOfFileEx to recreate shared memory regions. Add function
name to api_fatal output.
(shmat): Use NtMapViewOfSection to create shared memory region
top-down.
pointer-based newlib implementation.

Bump API minor number.

(ctype_iso.h): Include if _MB_EXTENDED_CHARSETS_ISO is set.
(ctype_cp.h): Include if _MB_EXTENDED_CHARSETS_WINDOWS is set.
(__ctype_ptr): Drop definition.
(__ctype_ptr__): De-constify. Mark as __EXPORT symbol.
(_ctype_): Add Cygwin-specifc asm define.
(__set_ctype): New function to set __ctype_ptr__ according to
current charset.

specific character class tables.
* libc/ctype/ctype_iso.h: New file containing ISO-8859-x
specific character class tables.
* libc/ctype/tolower.c (tolower): Reimplement to support any singlebyte
charset if one of the extended charsets is enabled.
* libc/ctype/toupper.c (toupper): Ditto.

(_toupper): Ditto.
(__ctype_ptr__): De-constify.
(toupper): Disable macro on systems supporting extended charsets.
(tolower): Ditto.
