- rename some macros and types defined in runetype.h.
- move declarations of some global symbols to rune.h from runetype.h.
- make sure the target sources use rune.h and mklocale use runetype.h.
I tested them on FreeBSD-4.6.2 box (./build.sh -m i386 tools).
have magic number check in locale modules.
rename: lib/libc/locale/setlocale_sb.c -> setlocale1.c
NOTE: this commit does not enable multibyte locale support, yet.
