Add PolicyManager, related classes and some config files

- PolicyManager
    Decide next layout by using occured event and current state
    based on policy table.
    This PolicyManger is reference and the OEMs can replace it.

- LayoutManager
    Change the current layout to the layout
    which decided by PolicyManager.

    NOTE:
    The functions of this class had been included in App class.
    The part of function of this class remain there yet.

- LowCanClient
    Receive the CAN signal from low level CAN service.

- app.db
    Define the applications name and its role.
    This file will be deleted
    when the names and roles can be given by other module.

- layout.cb
    Define the layouts and areas which are included by the layout.

- role.db
    Define the roles of the applications.
