	Revert the change which adds GError parameters to
	gimp_image_add_{channel,layer,vectors}():

	* app/actions/channels-commands.c
	* app/actions/edit-commands.c
	* app/actions/layers-commands.c
	* app/actions/vectors-commands.c
	* app/core/gimp-edit.c
	* app/core/gimpimage-duplicate.c
	* app/core/gimpimage-merge.c
	* app/core/gimpimage-quick-mask.c
	* app/core/gimpimage.[ch]
	* app/core/gimplayer-floating-sel.c
	* app/core/gimpselection.c
	* app/core/gimptemplate.c
	* app/display/gimpdisplayshell-dnd.c
	* app/text/gimptext-compat.c
	* app/tools/gimptexttool.c
	* app/tools/gimpvectortool.c
	* app/vectors/gimpvectors-import.c
	* app/widgets/gimpchanneltreeview.c
	* app/widgets/gimpitemtreeview.[ch]
	* app/widgets/gimplayertreeview.c
	* app/widgets/gimptoolbox-dnd.c
	* app/widgets/gimpvectorstreeview.c
	* app/xcf/xcf-load.c: revert.

	Instead, fix it at the PDB level:

	* app/core/gimpimage.c: turn the "added to wrong image" warning
	into a g_return_val_if_fail() assertion.

	* app/pdb/gimppdb-utils.[ch] (gimp_pdb_item_is_floating): add a
	"dest_image" parameter and fail if the passed item is not for this
	image.

	* tools/pdbgen/pdb/image.pdb
	* tools/pdbgen/pdb/layer.pdb
	* tools/pdbgen/pdb/paths.pdb: pass the dest image to
	gimp_pdb_item_is_floating().

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