GSettingsBackend: move 'has-unapplied' logic here

Browse Source 
Add GSettingsBackend API to allow any backend to have a 'has-unapplied'
property.  Remove the 'owner' hackery that was used for notifying of
changes to 'has-unapplied' and just use normal GObject notify (and wire
into that from the frontend).
