This patch reverts commit c6f9a9b8468b3746a3dec7ee2a0b7d84ec9fb44a
and update it.
Policy Manager decides next layout by inputed event and current state
based on the policy table.
And Policy Manager is plugin for Window Manager.
Therefore the OEMs can replace it.
This patch provides Policy Manager I/F as reference implementation
and does not have policy table.
Therefore Policy Manager updates each layers
to draw the applications in requested area
in accordance with just like activate/deactivate request.
