Services now must explicitly opt in to being accessed by isolated processes. Currently only the activity manager and surface flinger allow this. Activity manager is needed so that we can actually bring up the process; SurfaceFlinger is needed to be able to get the display information for creating the Configuration. The SurfaceFlinger should be safe because the app doesn't have access to the window manager so can't actually get a surface to do anything with. The activity manager now protects most of its entry points against isolated processes. Change-Id: I0dad8cb2c873575c4c7659c3c2a7eda8e98f46b0
