	* exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
	library-level package renaming, pass the declaration associated with
	the renaming's special debug variable to Qualify_Entity_Names to ensure
	that its encoded name is properly qualified.

	* exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
	occurring in the list of entities to qualify, and do not attempt to
	traverse an entity list in that case. Variables associated with
`	library-level package renamings can now occur in the table.

	* exp_dbug.ads: Revise documentation of the encoding for renaming
	declarations.
