UCLIBC_CTYPE_HEADER define is removed, as it always

equal to "include/bits/uClibc_ctype.h"

__CTYPE_unclassified and other similar __CTYPE_xxxx
constants are moved to separate include file,
bits/uClibc_charclass.h

Duplicate declaration of these constants is
removed from libc/misc/wctype/_wctype.c

Ugly re-inclusion trick in extra/locale/gen_wctype.c deleted

Large ifdefed-out chunk in extra/locale/gen_wctype.c removed

Move __CTYPE_isalnum() etc macros from uClibc_ctype.h
to their single user, extra/locale/gen_wctype.c
(can be simplified further)

Overall, no code changes (verified with objdump)
