Cleaned up the implementation of Surface and SurfaceSession to use more consistent naming and structure. Added JNI for all of the new surface flinger display API calls. Enforced the requirement that all Surfaces created by the window manager be named. Updated the display manager service to use the new methods. Change-Id: I2a658f1bfd0437e1c6f9d22df8d4ffcce7284ca2
