	Remove the external tag of a tagged type from the internal hash table.
	* exp_ch7.adb (Build_Cleanup_Statements): Update the comment on the
	expanded usage of the routine. Strenghten the check for Is_Master. Add
	processing for tagged types.
	(Build_Finalizer): Create all the necessary lists used in finalizer

	tagged types.
	(Expand_Cleanup_Actions): Rename the call to Has_Controlled_Objects to

	(Expand_N_Package_Body): Package bodies may need clean up code
	depending on whether they contain tagged types.
	(Expand_N_Package_Declaration): Package declarations may need clean up
	code depending on whether they contain tagged types.
	(Unregister_Tagged_Types): New routine. Search through a list of
	declarations or statements, looking for non-abstract Ada tagged types.
	For each such type, generate code to unregister the external tag.
	* exp_util.adb (Has_Controlled_Objects (Node_Id)): Renamed to
	Requires_Cleanup_Actions.
	(Requires_Cleanup_Actions (List_Id, Boolean)): New routine. Search
	through a list of declarations or statements looking for non-abstract

	* prj-env.adb (For_All_Source_Dirs.For_Project): Check if project Prj

	sources.

	* bindgen.adb (Gen_Adainit_Ada): Move the generation of the declaration
	of the No_Param_Proc acc-to-subp type used for initialization of
	__gnat_finalize_library_objects so that it's declared at library level
	rather than nested inside of the adainit routine.

	* sem_ch3.adb (Build_Derived_Record_Type): set Has_Private_Ancestor

	because of a private ancestor, the aggregate is illegal.
