it's either all-valid or it must start over with the fallback. That will
have to change in order to work with the proposed noError conversions. It
shouldn't be very hard, but needs thought as to the clearest and safest way
to code it.

In v4, it should be able to return an accurate count of valid bytes even
when the end crosses a character boundary.

It was actually completely broken if you tried to pass the special flags to
configure. I redesigned this part and it seems to work now.
