Add two more parameters to __check_pf.
* sysdeps/unix/sysv/linux/check_pf.c: When using the netlink
interface, determine whether IPv6 addresses are deprecated or
temporary. Create array of those addresses.
* inet/check_pf.c: Always tell caller there are no depracated
and temporary addresses.
* sysdeps/posix/getaddrinfo.c: Pretty printing.
(struct sort_result): Add source_addr_flags field.
(rfc3484_sort): Implement rule 3 and 7.
(in6aicmp): New function.
(getaddrinfo): Call __check_pf also when we need info about IPv6
source addresses. When creating array for sorting addresses,
look up deprecated and temporary addresses returned by __check_pf
and add flag if necessary.
