* include/ifaddrs.h: Remove in6ai_temporary.

	(struct in6addrinfo): Add index element.
	Declare __check_native.
	* inet/Makefile (aux): Add check_native.
	* sysdeps/unix/sysv/linux/check_native.c: New file.
	* sysdeps/unix/sysv/linux/check_pf.c: No need to recognize
	IFA_F_TEMPORARY.  Pass back ifa_index.
	* sysdeps/posix/getaddrinfo.c: Remove netlink compatibility code.
	(rfc3484_sort): Add new parameter.  Implement rule 7 correctly:
	call __check_native if necessary.
	(getaddrinfo): Fill in index field.  Use qsort_r instead of qsort
	to sort addresses.  Pass information about the results.
	* posix/tst-rfc3484.c: Adjust for addition of index field and change
	of rfc3484_sort interface.
	* posix/tst-rfc3484-2.c: Likewise.
