	* binde.adb (Elab_New): New elaboration order algorithm
	that is expected to cause fewer ABE issues. This is a work in
	progress. The new algorithm is currently disabled, and can be
	enable by the -dp switch, or by modifying the Do_Old and Do_New
	etc. flags and rebuilding. Experimental code is included to
	compare the results of the old and new algorithms.
	* binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
	can have multiple of these tables, so the old and new algorithms
	can coexist.
	* bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
	parameter of type array. This avoids the global variable, and
	allows bounds checking (which is normally defeated by the tables
	packages). It also ensures that the Elab_Order is read-only
	to Bindgen.
