        Calculate correct width for new text fields

        Tests:
        fast/forms/input-appearance-width.html
        fast/forms/input-appearance-minWidth.html

        * rendering/RenderTextField.cpp:
        (WebCore::RenderTextField::createDivStyle): Remove fixed width for text field.
        (WebCore::RenderTextField::calcMinMaxWidth): Added.  This calls RenderBlock::calcMinMaxWidth and 
         then uses the size attribute to determine what the maxWidth should be.
        * rendering/RenderTextField.h: Added calcMinMaxWidth.
        * rendering/render_theme_mac.h: Added adjustTextFieldStyle.
        * rendering/render_theme_mac.mm: 
        (WebCore::RenderThemeMac::adjustRepaintRect): Remove inflation of rect.  This is no longer necessary.
        (WebCore::RenderThemeMac::paintTextField): ditto.
        (WebCore::RenderThemeMac::setTextFieldCellState): change true to YES.
        (WebCore::RenderThemeMac::adjustTextFieldStyle): Added. This is the temporary home of the code to set the 
         right padding and margins.  When we flip the switch, this will go in html4.css.
