* 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.
