Restore audio settings and wifi.
Optimize backups by writing an entity only if the checksum of the data has changed.
Call into the hidden AudioService API to apply changed audio settings.
After restoring wifi data, make sure that the permissions and ownership are set
properly for the supplicant process to access it.
Locale isn't restoring properly - TODO added.
