* 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.
