	* makeutl.ads (Main_Config_Project): Moved to gpr_util.ads

	* prj.ads, prj.adb (Default_Language): Remove function, no longer used
	Replace components Compiler_Min_Options and Binder_Min_Options with
	Compiler_Required_Switches and Binder_Required_Switches in record
	Language_Config.
	Remove components Default_Language and Config in Project_Tree_Data,
	no longer used.

	* prj-attr.adb: New attributes Required_Switches (<language>) in
	packages Compiler and Binder.

	* prj-nmsc.adb: Major rewrite of the processing of configuration
	attributes for gprbuild. No impact on GNAT tools.

	* prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
	process configuration attributes: this is done in Prj.Nmsc.Check.
	(Recursive_Process): Make a full copy of packages inherited from project
	being extended, instead of a shallow copy.
	(Process_Project_Tree_Phase_1): New procedure
	(Process_Project_Tree_Phase_1): New procedure
	(Process): Implementation now uses the two new procedures

	* prj-util.adb (Executable_Of): Get the suffix and the default suffix
	from the project config, not the tree config that no longer exists.
