Rework: Window Manager handles by application

To manage role, surface, layer ... and other info more easily,
Window Manager handles info by application.
WMClient class holds infomation of application.
WMRequest class holds the request from application(trigger) and
the action list judged by policy manager.
The above info is in applist.

*applist
 Hold client list.
 And hold request list which comes from application to get the right of displaying.

*request
 The request from application and the Action judged from Policy Manager

*client
 Application information which has surface, role and so on.

*error
 Error code and error message.

Integration patch is going to be pushed after this commit.
