* resolv/nss_dns/dns-host.c (_nss_dns_gethostbyname3_r): Recognize

	ESRCH return value.
	(_nss_dns_gethostbyname4_r): Likewise.
	* resolv/res_init.c (__res_vinit): Initialize nscount to zero.
	* sysdeps/posix/getaddrinfo.c (gaih_inet): In case we use
	gethostbyname4_r, we don't have a separate IPv6 status, so copy
	the no_data variable.
