* sysdeps/posix/getaddrinfo.c (sort_results): Remove service_order

	field.  Use sockaddr_in6 for source_addr.
	(get_scope): Change type of parameter to sockaddr_in6.  Adjust.
	(match_prefix): Likewise.
	(get_label): Likewise.
	(get_precedence): Likewise.
	(rfc3484_sort): Change to use indirect access to results array.
	Adjust to use of sockaddr_in6.  Replace service_order test with
	simple index comparison.
	(getaddrinfo): Define order array.  Initialize it.  Don't initialize
	service_order field.  Adjust qsort_t calls.  Access sorted result
	array indirectly through order array.
	* posix/tst-rfc3484.c: Adjust for change of rfc3484_sort.
	* posix/tst-rfc3484-2.c: Likewise.
	* posix/tst-rfc3484-3.c: Likewise.
