Content providers are meant to be immutable, apart from very special cases, but in those cases they need to emit gdk_content_provider_content_changed(). Having a constructor that just uses a get_func invites abuse of this by not making developers aware of those requirments. In fact, all users in GTK failed to do this. Instead, code should use the GtkDragSource::prepare signal to create content providers when needed. The same problem exists with gdk_content_provider_new_with_formats(), but this commit doesn't touch that.
