SurfaceFlinger: Add support for non-privileged clients.

Allow clients without privilege to create child layers through scoped
connections. We enable this in preparation for allowing SurfaceView
to bypass the WindowManager. We include support for reparenting of
all of a layer's children for the WindowManager to use in cases where
one surface is replacing another (while keeping its children around).

Test: Tested with corresponding SurfaceView modifications.
