Expose it partly (in internal headers anyway), and pass a vtable for the data source functions, the wayland vfuncs just delegate operations on the wl_data_source resource. The resource has been also made optional, although it'll be present on all data sources from wayland clients. The ownership/lifetime of the DnD data source has also changed a bit, belonging now to the MetaWaylandDataDevice like the selection one does, as we can't guarantee how long it will be needed after the grab is finished, it will be left inert and replaced the next time DnD is started at worst. This allows the creation of custom/proxy data sources, which will turn out useful for X11 selection interoperation. https://bugzilla.gnome.org/show_bug.cgi?id=738312
