This is a huge reorganization of GtkDropTarget. I did not know how to split this up, so it's unfortunately all one commit. Highlights: - Split GtkDropTarget into GtkDropTarget and GtkDropTargetAsync GtkDropTarget is the simple one that only works with GTypes and offers a synchronous interface. GtkDropTargetAsync retains the full old functionality and allows handling mime types. - Drop events are handled differently Instead of picking a single drop target and sending all DND events to it, every event is sent to every drop target. The first one to handle the event gets to call gdk_drop_status(), further handlers do not interact with the GdkDrop. Of course, for the ultimate GDK_DROP_STARTING event, only the first one to accept the drop gets to handle it. This allows stacking DND event controllers that aren't necessarily interested in handling the event or that might decide later to drop it. - Port all widgets to either of those Both have a somewhat changed API due to the new event handling. For the ones who should use the sync version, lots of cleanup was involved to operate on a sync API.
