Provide a softer transition to the overflow-everywhere world for devices with menu keys. The panel menu will still be used on these devices in response to a menu key press even in the presence of an action bar with overflow. Fix a few lingering bugs around dispatching the open-overflow transition that caused problems with this along the way. Change-Id: I9d77c70f6d15c47160ac06292984101d619c44e6
