commit 3fcec02f63b1894c51157c3a69a799a137338e84
Author: Mitsuru Oshima <oshima@chromium.org>

Workspace protocol update:

* Sends insets in client's pixel size.
* Explicitly sends stable insets (unaffected by shelf state)
  This will fix the issue where the stable insets is incorrect when
  the shelf side has changed during auto hide.
* Unify display /workspace into one WorkspaceInfo.
 Removed unnecessary "scale_factor".
* Added systemui_visibility to nofity the state of shelf.
  This is necessary to compute correct contentInsets when the shelf
  is set to autohide by a user.
