[gtk/dnd-gestures: 7/10] Remove traditional drag source API



commit 27ea6a41e7ef4e4cc8334a41a2b9763818145081
Author: Matthias Clasen <mclasen redhat com>
Date:   Wed Jan 1 02:25:18 2020 -0500

    Remove traditional drag source API
    
    gtk_drag_source_set, gtk_drag_begin, related apis
    and the GtkWidget source-side signals have all been
    replaced by GtkDragSource.
