gdk: Allow internal management of source-side DnD We've traditionally left GTK+ to handle the input side of things, letting GDK only manage the windowing-specific messaging. This way of splitting responsibilities is not compatible however with some backends, we must fold then input management at the DnD stage into GDK (and backends) domain. The gdk_drag_context_manage_dnd() call is meant to be the entry point for this mode of operation, if the drag and drop operation becomes managed, the caller (i.e. gtkdnd.c) doesn't need to perform grabs, nor manage input events itself. As a consequence of this, different aspects now belong to the backend GdkDragContext implementation: - Because the caller doesn't see keyboard events anymore, keyboard navigation must be managed in GDK, so is the decision of the current action based on modifiers/button pressed. - Because the caller won't see input events in general, the lifetime of the drag and drop operation is now communicated through the ::drop-performed, ::dnd-finished and ::cancel events - Because the caller doesn't participate anymore on the action being chosen, the pointer cursor must be set by the backend. The caller is rather notified of the final action through the ::action signal. The caller is still responsible of dealing with the corresponding GdkSelection, ensuring its ownership and communicating the supported mimetypes.

This fixes the notebook tab DnD feature, where we rely on GTK_DRAG_RESULT_NO_TARGET. In the wayland side, unfortunately we can't honor either NO_TARGET nor USER_CANCELLED, we don't know of the latter, so we could return false positives on the former. https://bugzilla.gnome.org/show_bug.cgi?id=761954
