* libc/include/sys/_types.h (_mbstate_t): Changed to use
unsigned char internally.
* libc/sys/linux/sys/_types.h: Ditto.
* libc/include/sys/reent.h
* libc/stdlib/mblen.c (mblen): Use function-specific state
value from default reentrancy structure.
* libc/stdlib/mblen_r.c (_mblen_r): If return code from
_mbtowc_r is less than 0, reset state __count value and
return -1.
* libc/stdlib/mbrlen.c (mbrlen): If the input state pointer
is NULL, use the function-specific pointer provided in the
default reentrancy structure.
* libc/stdlib/mbrtowc.c: Add reentrant form of function.
If input state pointer is NULL, use function-specific area
provided in reentrancy structure.
* libc/stdlib/mbsrtowcs.c: Ditto.
* libc/stdlib/wcrtomb.c: Ditto.
* libc/stdlib/wcsrtombs.c: Ditto.
* libc/stdlib/mbstowcs.c: Reformat.
* libc/stdlib/wcstombs.c: Ditto.
* libc/stdlib/mbstowcs_r.c (_mbstowcs_r): If an error occurs,
reset the state's __count value and return -1.
* libc/stdlib/mbtowc.c: Ditto.
* libc/stdlib/mbtowc_r.c (_mbtowc_r): Add restartable functionality.
If number of bytes is used up before completing a valid multibyte
character, return -2 and save the state.
* libc/stdlib/wctomb_r.c (_wctomb_r): Define __state as __count
and change some __count references to __state for clarity.
