Add new window manager type for a hacking second-level media surface. 

This adds a new window type that is a surface that sits between the
current media type and the application window, in theory allowing you
to have two surface views in your hierarchy and control their
Z-ordering.  There is also another hidden API on SurfaceView to set
the type of your window.

All a big hack, but for the good of the commonwealth!
