Steps to reproduce:

Launch weston
Launch a flower
Launch weston-terminal and make it fullscreen
Go to exposay and click on the flower

The flower should be drawn above the fullscreen terminal but it is actually behind.

    desktop-shell: Properly handle lowered fullscreen surfaces
    lower_fullscreen_surface() was removing fullscreen surfaces from
    the fullscreen layer and inserting them in the normal workspace
    layer. However, those fullscreen surfaces were never put back in
    the fullscreen layer, causing bugs such as unrelated surfaces
    being drawn between a fullscreen surface and its black view.
    Change the lower_fullscreen_surface() logic so that it lowers
    fullscreen surfaces to the workspace layer *and* hides the
    black views. Make this reversible by re-configuring the lowered
    fullscreen surface: when it is re-configured, the black view
    will be shown again and the surface will be restacked in the
    fullscreen layer.
