Add PolicyManager as plugin
PolicyManager decides next layout by using occured event and current state based on the policy table. And PolicyManager is plugin for WindowManager. Therefore the OEMs can replace it. This patch provides PolicyManager I/F as reference implementation and does not have policy table. Therefore PolicyManager updates each layers to draw the applications in normal.full area in accordance with just like activate/deactivate request. [APIs of PolicyManager class] - int initialize(void) Initialize PolicyManger. input: none output: 0(success), -1(error) - void registerCallback(CallbackTable callback_table) Register callback functions. input: the pointers of callback handlers output: none "CallbackTable" type is as follows: typedef struct { Handler onStateTransitioned; Handler onError; } CallbackTable; "Handler" type is as follows: using Handler = std::function<void(json_object *)>; - int setInputEventData(json_object *json_in) Set input event data for the policy table. input: input event data as json_object output: 0(success), -1(error) - int executeStateTransition(void) Execute state transition by using set input event data. input: none output: 0(success), -1(error) - void undoState(void) Undo state only once per once state transition. input: none output: none [Callbacks of PolicyManager class] - void onStateTransitioned(json_object *json_out) When state transition succeeds, this callback is called. The argument json_out has the state after transition. - void onError(json_object *json_out) When state transition fails, this callback is called. The argument json_out has the error information like message, inputed event datas and etc..
