* Versions.def: Add GLIBC_2.9 to libresolv.

	* include/resolv.h: Remove hidden proto declarations for __ns_*
	functions.  Add them for __dn_count_labels and __p_secstodate.

	Define ns_msg_getflags macro here.
	* resolv/res_debug.c: Add hidden definition for __dn_count_labels
	and __p_secstodate.
	* resolv/Versions: Export functions from <arpa/nameser.h> from
	libresolv in version GLIBC_2.9.
	* resolv/ns_name.c: Integrate changes from bind 9.5.0.  Add necessary
	hidden definitions.
	* resolv/ns_netint.c: Likewise.
	* resolv/ns_parse.c: Likewise.
	* resolv/ns_print.c: Likewise.
	* resolv/ns_samedomain.c: Likewise.
	* resolv/ns_ttl.c: Likewise.

	* resolv/arpa/nameser.h: Likewise.  Remove macros which redirect
	function calls.
	* resolv/nss_dns/dns-canon.c (_nss_dns_getcanonname_r): Use __ns_get16
	instead of ns_get16.
	* resolv/nss_dns/dns-host.c (getanswer_r): Use __ns_get16 and
	__ns_get32 instead of ns_get16 and ns_get32 respectively.
	(gaih_getanswer_slice): Likewise.
