        Deployed EditingStyle in selectionHasStyle and selectionStartHasStyle.
        This allowed us to move triStateOfStyle from Editor.cpp to EditingStyle.cpp.

        Also changed the argument lists of selectionHasStyle and selectionStartHasStyle
        to take a property id and a value instead of a CSSMutableStyleDeclaration to cleanup
        call sites of these two functions.

        * WebCore.exp.in: Updated the signature of selectionHasStyle. No longer exports
        selectionStartHasStyle because it's not called anywhere outside of WebCore.
        * WebCore.order: Ditto.
        * editing/EditingStyle.cpp:
        (WebCore::EditingStyle::EditingStyle): Added a new constructor that takes a property id
        and a property value.
        (WebCore::EditingStyle::triStateOfStyle): Moved from Editor.cpp.
        * editing/EditingStyle.h:
        (WebCore::EditingStyle::create): Added.
        * editing/Editor.cpp:
        (WebCore::Editor::selectionStartHasStyle): Takes a property id and a value instead of
        a CSSStyleDeclaration.
        (WebCore::Editor::selectionHasStyle): Ditto.
        * editing/Editor.h: Updated the signatures of selectionStartHasStyle and selectionHasStyle.
        * editing/EditorCommand.cpp:
        (WebCore::executeToggleStyle): Calls selectionStartHasStyle and selectionHasStyle.
        (WebCore::stateStyle): Ditto.
        * page/ContextMenuController.cpp:
        (WebCore::ContextMenuController::checkOrEnableIfNeeded): Ditto.
