Remove the tolerant parsing function and make the recoder tolerant

Remove the tolerant parsing function and make the recoder tolerant

The reason for this change is that the strict parser made little sense
to exist. What would the recoder do if it was passed an invalid
string?

I believe that the tolerant recoder is more efficient than the
correcting code followed by the strict recoder. This makes the recoder
more complex and probably a little less efficient, but it's better in
the common case (tolerant that doesn't need fixes) and in the worst
case (needs fixes).
