Subject: 	* libc/stdio/vfprintf.c: Include ../stdlib/local.h.  Replace
 call to 	_mbtowc_r with direct call to __mbtowc. 	*
 libc/stdio/vfscanf.c: Ditto. 	* libc/stdlib/btowc.c: Include local.h. 
 Replace call to _mbtowc_r 	with direct call to __mbtowc. 	*
 libc/stdlib/mblen.c: Ditto. 	* libc/stdlib/mblen_r.c: Ditto. 	*
 libc/stdlib/mbrtowc.c: Ditto. 	* libc/stdlib/mbstowcs_r.c: Ditto. 	*
 libc/stdlib/mbtowc.c: Ditto. 	* libc/stdlib/wcrtomb.c: Include local.h. 
 Replace call to _wctomb_r 	with direct call to __wctomb. 	*
 libc/stdlib/wcsnrtombs.c: Ditto. 	(_wcsnrtombs_r): Ditto. 	*
 libc/stdlib/wcstombs_r.c: Ditto. 	* libc/stdlib/wctob.c: Ditto. 	*
 libc/stdlib/wctomb.c: Ditto.

	* libc/stdlib/mbrtowc.c (mbrtowc): Implement independently from
	_mbrtowc_r, unless PREFER_SIZE_OVER_SPEED or __OPTIMIZE_SIZE__ are
	defined.
	* libc/stdlib/wcrtomb.c (wcrtomb): Implement independently from
	_wcrtomb_r, unless PREFER_SIZE_OVER_SPEED or __OPTIMIZE_SIZE__ are
	defined.

	* libc/stdlib/mbtowc_r.c (__utf8_mbtowc): Drop unnecessary test for
	ch >= 0.
