	Moved the calls to floating_sel_relax()/rigor() from various
	places to two single spots in the core where they are actually
	needed. Fixes bug #138356 (which was caused by the projection
	being triggered in the middle of changing the floating selection's
	size or the size of the drawable it is attached to). This commit
	effectively removes floating selection fiddling from the core's
	public API.

	* app/core/gimpdrawable.[ch] (gimp_drawable_has_floating_sel): new
	function which returns TRUE if there is a floating selection
	attached to the drawable.

	* app/core/gimpdrawable.c (gimp_drawable_translate)
	(gimp_drawable_set_tiles_full): if the drawable *has* a floating
	selection, relax/rigor it before/after modifying the drawable.

	* app/core/gimplayer.c (gimp_layer_translate)
	(gimp_layer_set_tiles): if the layer *is* the floating selection,
	relax/rigor it before/after modifying it.

	* app/core/gimpdrawable-transform.c
	* app/core/gimpimage-convert.c
	* app/core/gimpimage-crop.c
	* app/core/gimpimage-flip.c
	* app/core/gimpimage-resize.c
	* app/core/gimpimage-rotate.c
	* app/core/gimpimage-scale.c
	* app/gui/layers-commands.c
	* app/tools/gimpeditselectiontool.c
	* tools/pdbgen/pdb/layer.pdb: removed calls to
	floating_sel_rigor()/relax() all over the place. Also removed
	lots of undo groups which are obsolete now.

	* app/pdb/layer_cmds.c: regenerated.
