	* app/core/gimplayer.[ch] (gimp_layer_add_mask): add GError
	parameter and replace g_message() by g_set_error().

	* app/core/gimplayermaskundo.c
	* app/xcf/xcf-load.c
	* app/actions/layers-commands.c: pass NULL errors since these
	places know what they are doing. Ha ha...

	* tools/pdbgen/pdb/layer.pdb
	* tools/pdbgen/pdb/image.pdb: pass the error so we get more real
	error messages for failed PDB calls.

	* app/pdb/image-cmds.c
	* app/pdb/layer-cmds.c: regenerated.
