        REGRESSION: New text fields need to send callbacks used by autocomplete

        Fix for:
        http://bugzilla.opendarwin.org/show_bug.cgi?id=8156
        FrameMac::submitForm is busted after Vector changes

        * bindings/objc/DOMHTML.mm:
        (-[DOMHTMLInputElement _rectOnScreen]): Use boundingBox method so this no longer relies on an NSTextField.  
        The old code is no longer needed because this method was used by autocomplete, and that was not enabled for password or search fields.
        (-[DOMHTMLInputElement _replaceCharactersInRange:withString:selectingFromIndex:]): New implementation that uses setValue and setSelectionRange
        instead of NSTextField specific code.
        (-[DOMHTMLInputElement _selectedRange]): Creates range by calling selectionStart and selectionEnd on the input element.
        (-[DOMHTMLInputElement _setAutofilled:]): Provides a way for the autofill code to set a flag on the input element so
         it knows when its value is set by autofill.  This is how we change the background color.
        * bindings/objc/DOMPrivate.h: Removed _displayedValue, _setDisplayedValue, _setBackgroundColor since these are no
         longer needed for the new text field implementation, and aren't used for remaining NSView-style password and search fields.
         Added _setAutofilled method.
        * bridge/mac/FrameMac.h: Added virtual clearRecordedFormValues and recordFormValue.  These were moved into Frame.cpp recently, which broke
        how Safari asked to add form values to the keychain.

        * bridge/mac/FrameMac.mm:
        (WebCore::createNSDictionary): Added. Converts a hashmap to an NSDictionary for m_formValuesAboutToBeSubmitted.  This is needed to fix the submit form bug.
        (WebCore::selectorForKeyEvent): Added.  This helper function converts key events into selectors that the autocomplete code needs to know about.
        (WebCore::FrameMac::FrameMac):
        (WebCore::FrameMac::submitForm): Convert saved form and formValues into DOMElement and NSMutableDictionary.
        (WebCore::FrameMac::textFieldDidBeginEditing): Added so the input element can send this notification over the bridge.
        (WebCore::FrameMac::textFieldDidEndEditing): ditto.
        (WebCore::FrameMac::textDidChangeInTextField): ditto.
        (WebCore::FrameMac::doTextFieldCommandFromEvent): ditto. Also calls selectorForKeyEvent.
        (WebCore::FrameMac::textWillBeDeletedInTextField): ditto.
        * page/Frame.cpp:
        (WebCore::Frame::textFieldDidBeginEditing): ditto.
        (WebCore::Frame::textFieldDidEndEditing): ditto.
        (WebCore::Frame::textDidChangeInTextField): ditto.
        (WebCore::Frame::doTextFieldCommandFromEvent): ditto.
        (WebCore::Frame::textWillBeDeletedInTextField): ditto.
        * page/Frame.h: ditto.
        * platform/PlatformString.h: (WebCore::String::replace): Added to use an existing version of StringImpl::replace.

        * rendering/RenderTextField.cpp:
        (WebCore::RenderTextField::setSelectionRange): Setting the selection here should close the typing command.
        (WebCore::RenderTextField::subtreeHasChanged): Calls textDidChangeInTextField.

        * dom/Document.cpp: (WebCore::Document::setFocusNode): Calls dispatchFocusEvent and dispatchBlurEvent instead of directly dispatching the events.  This gives the node a chance to do other work before dispatching the event.

        * dom/EventTargetNode.cpp:
        (WebCore:: EventTargetNode::dispatchFocusEvent): Added.
        (WebCore:: EventTargetNode::dispatchBlurEvent): Added.
        * dom/EventTargetNode.h:

        * html/HTMLInputElement.cpp:
        (WebCore::HTMLInputElement::init): initializes m_autofilled.
        (WebCore::HTMLInputElement::dispatchFocusEvent): Calls textFieldDidBeginEditing and then calls up to the base class
        (WebCore::HTMLInputElement::dispatchBlurEvent): Calls textFieldDidEndEditing and then calls up to the base class
        (WebCore::HTMLInputElement::defaultEventHandler): For keypress events, calls doTextFieldCommandFromEvent so the form delegate will
        have a chance to say whether or not it is going to handle the event.
       (WebCore::HTMLInputElement::isKeyboardFocusable): Uses isNonWidgetTextField instead of checking the inputType.
        (WebCore::HTMLInputElement::isMouseFocusable): ditto.
        (WebCore::HTMLInputElement::focus): ditto.
        (WebCore::HTMLInputElement::constrainValue): Uses isTextField instead of checking inputType.
        * html/HTMLFormElement.cpp: (WebCore::HTMLFormElement::submit): ditto.
        * html/HTMLInputElement.h:
        (WebCore::HTMLInputElement::isTextField): Added. Checks for TEXT, PASSWORD, and SEARCH
        (WebCore::HTMLInputElement::isNonWidgetTextField): Added.  Checks for all converted controls.
        (WebCore::HTMLInputElement::autofilled): Added.
        (WebCore::HTMLInputElement::setAutofilled): Added.
        * html/HTMLTextFieldInnerElement.cpp: (WebCore::HTMLTextFieldInnerElement::defaultEventHandler): Uses isNonWidgetTextField instead of checking the inputType.

        * editing/DeleteSelectionCommand.cpp: (WebCore::DeleteSelectionCommand::doApply):
         If the deletion is occuring in a text field, call textWillBeDeletedInTextField so the frame can
         call across the bridge to notify the form delegate.

        * css/css_base.cpp: (WebCore::CSSSelector::extractPseudoType): Added autofill string for "-khtml-autofill".
        * css/css_base.h: (WebCore::CSSSelector::): Added PseudoAutofill to enum.
        * css/cssstyleselector.cpp:
        (WebCore::CSSStyleSelector::checkOneSelector): Added case for PseudoAutofill that checks the input element's autofilled flag.
        (WebCore::CSSStyleSelector::getColorFromPrimitiveValue): Changed  -webkit-focus-ring-color to -khtml-focus-ring-color for consistency.
        * css/html4.css: Added background-color and background-image for input:-khtml-autofill style.
         Changed -webkit-focus-ring-color to -khtml-focus-ring-color for consistency.
        * css/CSSValueKeywords.in: ditto.
        * css/cssparser.cpp:
        (WebCore::CSSParser::parseValue): ditto.
        (WebCore::CSSParser::parseShadow): ditto.
