------- Additional Comments from TAMURA, Kent <tkent at chromium.org>
Sorry for the large patch.
* The most of changes in HTMLInputElment, InputElment, WMLInputElement are
trivial. (removal of unused parameters)
* We have a bug about maxlength.  The patch accidentally fixes it because of
RenderTextControlSingleLine::updateFromElement() change. 
input-text-maxlength-expected.txt had wrong expected data.
