        REGRESSION: selectionStart/End return 0 for input element once it no longer has focus

        Implemented onSelect for new text fields and textareas.  Also fixed selection restore
        behavior to better match other browsers and Safari 2.0 behavior.

        Tests:
        * fast/forms/input-selection-restore.html
        * fast/forms/input-selection-hidden.html
        * fast/forms/onselect-textarea.html
        * fast/forms/onselect-textfield.html

        * html/HTMLInputElement.h: (WebCore::HTMLInputElement::cacheSelection): Added.
        * html/HTMLInputElement.cpp:
        (WebCore::HTMLInputElement::init): Initializes cached selection.
        (WebCore::HTMLInputElement::selectionStart): If this element doesn't have focus, return the cached selection value.
        (WebCore::HTMLInputElement::selectionEnd): ditto.
        (WebCore::HTMLInputElement::setValue): Restore a caret at the starting point of the old selection.  Matches Safari 2.0 behavior.

        * html/HTMLTextAreaElement.h: (WebCore::HTMLTextAreaElement::cacheSelection): Added.
        * html/HTMLTextAreaElement.cpp:
        (WebCore::HTMLTextAreaElement::HTMLTextAreaElement): Initializes cached selection.
        (WebCore::HTMLTextAreaElement::selectionStart): If this element doesn't have focus, return the cached selection value.
        (WebCore::HTMLTextAreaElement::selectionEnd): ditto.
        (WebCore::HTMLTextAreaElement::focus): If this is the first focus, set a caret at the end of the text.  Otherwise,
        restore the cached selection.  This matches other browsers' behavior.
        (WebCore::HTMLTextAreaElement::setValue): Restore a caret at the starting point of the old selection.  Matches Safari 2.0 behavior.

        * page/Frame.h: Added notifyRendererOfSelectionChange method.
        * page/Frame.cpp:
        (WebCore::Frame::notifyRendererOfSelectionChange): Added.  Calls selectionChanged for text fields and textareas.  Forwards a userTriggered
        argument so selectionChanged knows whether or not to fire onSelect.
        (WebCore::Frame::setSelection): Calls notifyRendererOfSelectionChange(false).  This gets called for all selection changes, so the renderer
        can always update its cached selection values.
        (WebCore::Frame::handleMouseReleaseEvent): Calls notifyRendererOfSelectionChange(true) so onSelect will get fired when the user is done
        making a selection with the mouse.
        * bridge/mac/WebCoreFrameBridge.mm:
        (-[WebCoreFrameBridge alterCurrentSelection:direction:granularity:]): Calls notifyRendererOfSelectionChange(true) so onSelect gets
        fired when the user makes a selection with the keyboard.
        (-[WebCoreFrameBridge alterCurrentSelection:verticalDistance:]): ditto.

        * rendering/RenderTextField.h: Add userTriggered parameter to selectionChanged.
        * rendering/RenderTextField.cpp:
        (WebCore::RenderTextField::setSelectionRange): For visibility:hidden, cache the selection and
        return early since we won't be able to actually set the selection.
        (WebCore::RenderTextField::selectionChanged): Caches the selection.
        If the selection is a range, and its triggered by user action, then fire the onSelect event.
