xr_tabls.adb, [...]: Update to latest lib-xref.ads Fix handling of parameters.

Browse Source 
2010-06-23  Arnaud Charlet  <charlet@adacore.com>

	* xr_tabls.adb, xref_lib.adb: Update to latest lib-xref.ads
	Fix handling of parameters.
	Add protection against unexpected cases.
	* sem_ch6.adb (Create_Extra_Formals): Use suffix "L" instead of "A" for
	access level, since "A" suffix is already used elsewhere. Similarly,
	use suffix "O" instead of "C" for 'Constrained since "C" suffix is used
	for xxx'Class.
