lib-load.ads: Minor reformatting.

	* lib-load.ads: Minor reformatting.
	* sinfo.ads (Library_Unit): Update comment.
	* lib.ads (Notes): Simplify. The Unit component in Notes_Entry
	is redundant. Instead used the pragma Node_Id directly as the
	element type.

	* lib.adb (Store_Note): Store only notes that do not come from
	an instance, and that are in the extended main source unit.
	* lib-writ (Write_Unit_Information): Annotations from subunits
	must be emitted along with those for the main unit, and they
	must carry a specific file name.
	* ali.ads (Notes_Record): Use a File_Name_Type instead of a
	Unit_Id for the source file containing the pragma, as in the
	case of annotations from subunits we might not have a readily
	available unit id.
	* ali.adb (Scan_ALI): Account for above change in data structure.
