	* prj-proc.adb, prj-nmsc.adb (Check_Naming_Schemes): split into several
	smaller subprograms.
	Renamed to Check_File_Naming_Schemes to avoid confusion with the
	other Check_Naming_Schemes functions that plays a totally different
	role.
	(Check_Unit_Based_Lang, Check_File_Based_Lang): new subprograms,
	extracted from the above. These were partially rewritten to avoid
	unnecessary code and temporary variables.
	(Compute_Unit_Name): new subprogram, merge of Check_Unit_Based_Lang
	and Get_Unit (which for now still exist since they contain mode-specific
	code)
