there is no need to zero-fill an mbstate_t object in the caller;
mbsrtowcs will automatically treat a null pointer as the initial
state.
|
|
negative values of wchar_t need to be treated in the non-ASCII case so
that they can properly generate EILSEQ rather than getting truncated
to 8bit values and stored in the output.

these changes fix at least two bugs:
- misaligned access to the input as uint32_t for vectorized ASCII test
- incorrect src pointer after stopping on EILSEQ
in addition, the text of the standard makes it unclear whether the
mbstate_t object is to be modified when the destination pointer is
null; previously it was cleared either way; now, it's only cleared
when the destination is non-null. this change may need revisiting, but
it should not affect most applications, since calling mbsrtowcs with
non-zero state can only happen when the head of the string was already
processed with mbrtowc.
finally, these changes shave about 20% size off the function and seem
to improve performance by 1-5%.

this type was removed back in 5243e5f1606a9c6fcf01414e ,
because it was removed from the XSI specs.
however some apps use it.
since it's in the POSIX reserved namespace, we can expose it
unconditionally.
