Currently IsCrosSetting, etc, are all implemented regardless. Personally I would
re-factor this code to have a prefs_util_chromeos derived class that had all of
the chromeos specific code, but for now I think it is fine as-is.

                                     const base::Value* value);
 
   Profile* profile_;  // weak
 };
 
 }  // namespace extensions
