nuke one struct initializer which was invisibly becoming a memset -
this improves speed by x2:

remove old-style-C function params declarations;
change re_comp_buf from struct to pointer (more static build friendly)

1. static char rcsid[] = "$NetBSD: ..."
2. /* @(#)s_scalbn.c 5.1 93/09/24 */
3. #ifdef __STDC__
No code changes (verified with objdump)

stop using macros with hidden parameter - that's evil;
reformat broken indenting (it was not matching the number of {}s);
fix format warnings (int vs size_t vs long)
No code changes (verified with objdump)

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)

implement inline versions of some of them.
Enable only those which result roughly in the same
code size as using out-or-line versions.
None of this affects users, installed headers won't have
any trace of it.
