	cp_pedwarn, and cp_compiler_error to error, warning, pedwarn, and
	internal_error respectively.  Make cp_deprecated into a macro.
	Don't define cp_printer typedef or declare cp_printers.

	print_nested_name_specifier, and definition of cp_printers.
	(locate_error): New function.
	(cp_error_at, cp_warning_at, cp_pedwarn_at): Moved here and
	rewritten in terms of locate_error and diagnostic.c.
