Sergey Biryukov ad7bc20cb1 Customizer: Introduce WP_Customize_Control::active() method to determine whether the control is relevant to the current context (i.e. to the current URL being previewed).
Control can indicate its active state by a subclass overriding the 'active_callback' method, by supplying a callable 'active_callback' argument into the control's constructor, or by filtering 'customize_control_active'.
