3d9c7fc998
Change the implementation of AppStateAppOpsBridge to handle multiple requested permissions in one operation due to the merging of CHANGE_NETWORK_STATE permission with WRITE_SETTINGS. This change will affect the packages that will be listed under the "Write system settings" option in Settings->Apps->[Gear/Cog]. Change-Id: I7d2304d2846b6f505a7b1c3fcf53e7a9bd184ed5
