commit 614a167430f1d98750f07116c945238103ad861e
Author: Elliot Glaysher <erg@chromium.org>

[mash] Use an aura::Window property for hide shelf in fullscreen mode.

This removes another direct usage of ash::wm::WindowState from
//chrome/. It also reworks the signaling mechanism in
ImmersiveModeControllerAsh so that on fullscreen change events, we
correctly update the shelf visibility without directly linking with
ash code.
