	* app/gegl/gimpoperationlevels.[ch]
	(gimp_operation_levels_map_input): new utility function which maps
	a single value.

	* app/tools/gimplevelstool.[ch] (levels_update_adjustments): use the
	new function to create the input arrays for gimp_color_bar_set_buffer().

	Removed the Levels struct from the GimpLevelsTool struct and only
	use it in map() when needed.

	* app/base/levels.[ch]: remove obsolete API and struct members.
