This will get the 'user' value from the database (ie: the one that the user has control over). Provide a default implementation that chains to ->read(). That will work for all of our internal backends which don't have a concept of layering or lockdown. The delayed backend implments "user value" by returning anything that's in the changeset (incuding an explicit NULL) or chaining up otherwise. We will use this for g_settings_get_user_value(). https://bugzilla.gnome.org/show_bug.cgi?id=668233
