This changes the backup service to use the settings provider instead
of system properties, correspondingly making it off by default and
allowing specific devices to define the transport. Also tweaks
the permission checks to use the permission symbol instead of raw
strings.
This requires some corresponding changes in the vendor projects.
Network Location Provider requires user opt-in, so it should be disabled by default
and only enabled if the user agrees to the terms of service and privacy policy.
Use GPS as default location provider instead.
