[PATCH][BZ #13928] Use minimum ttl value from dns query

[Siddhesh Poyarekar]

Hi,

I missed the case of host queries using getaddrinfo() in my last patch.
I've attached an updated patch with these changes. New ChangeLog below.
Tested with same scenarios as earlier, except that the command now is:

getent ahosts bad.foo.net

instead of:

getent hosts bad.foo.net

Regards,
Siddhesh

	* resolv/nss_dns/dns-host.c (getanswer_r): Also consider ttl
	from a CNAME entry and return the minimum ttl for the query.
	(gaih_getanswer_slice): Likewise.
