All code interacting with Objective-C objects should now use Automated Reference Counting rather than manual memory management or Garbage Collection. Because ARC prohibits C-structs from containing references to Objective-C objects, all such fields are now typed 'gpointer'. Setting and gettings Objective-C fields on such a struct now uses explicit __bridge_* calls to tell ARC about object lifetimes. https://bugzilla.gnome.org/show_bug.cgi?id=777847
