Show user dialog for BT connection and phonebook access
Show user dialog for incoming BT connection requests from unknown devices. Move phone book access permission dialog from bluetooth to settings. The permision dialog pops up to the screen properly instead of always as notification. AT+CPBR will also use the permission dialog to ask for user permission. bug 4489572 Change-Id: Ic1e74b2a9416a462cac4f519240a313691da90c4
