app, libgimp, pdb, plug-ins: new GimpGroupLayer class in libgimp. Also: - renaming gimp_layer_group_new() to gimp_group_layer_new() in order to keep the same name as in core code (i.e. GimpGroupLayer, not GimpLayerGroup). - renaming gimp_image_merge_layer_group() to gimp_group_layer_merge() - new functions: gimp_procedure_add_group_layer_argument(), gimp_procedure_add_group_layer_aux_argument() and gimp_procedure_add_group_layer_return_value(). This can be tested, e.g. in Python with these calls: ```py i = Gimp.get_images()[0] g = Gimp.GroupLayer.new(i, "hello") i.insert_layer(g, None, 1) g2 = Gimp.GroupLayer.new(i, "world") i.insert_layer(g2, g, 1) g.merge() ``` This was work started long ago, stored in an old stash which I finally finish now! :-)

libgimp: add G_GNUC_WARN_UNUSED_RESULT to several functions. Functions creating a new GeglBuffer should trigger a warning if the result if unused, because this is potentially a big memory leak. Similarly objects created by functions creating new layers should be handled (usually by adding the layer to the image with gimp_image_insert_layer()), because they also come with a buffer and possibly quite some important memory leak.
