Update.
2000-07-18  Mark Kettenis  <kettenis@gnu.org>

	Update resolver code to BIND 8.2.3-T5B.

	* resolv/Versions [GLIBC_2.2] (libc): Add __res_init and
	__res_nclose.
	[GLIBC_2.2] (libresolv): Add __dn_expand, __ns_samename,
	__res_mkquery, __res_nsend, __res_query, __res_querydomain and
	__res_search.
	* resolv/Banner: BIND-8.2.3-T5B.

	* resolv/base64.c: Update from BIND 8.2.3-T5B.
	* resolv/herror.c: Likewise.
	* resolv/inet_addr.c: Likewise.
	* resolv/inet_net_ntop.c: Likewise.
	* resolv/inet_net_pton.c: Likewise.
	* resolv/inet_neta.c: Likewise.
	* resolv/inet_ntop.c: Likewise.
	* resolv/nsap_addr.c: Likewise.
	* resolv/inet_pton.c: Likewise.  Reject a few more more invalid
	IPv6 addresses (ISC bug #520).

	* resolv/ns_name.c: Avoid emitting RCS ID in object file.
	* resolv/ns_parse.c: Likewise.
	* resolv/ns_netint.c: Likewise.
	* resolv/ns_samedomain.c: Likewise.
	* resolv/ns_ttl.c: Likewise.
	* resolv/ns_print.c: Update from BIND 8.2.3-T5B.  Avoid emitting
	RCS ID in object file.

	* resolv/res_debug.c: Update from BIND 8.2.3-T5B.
	* resolv/res_mkquery.c: Likewise.
	* resolv/res_query.c: Likewise.
	* resolv/res_init.c: Likewise.
	(res_setoptions): Mark internal.
	* resolv/res_send.c: Likewise.
	[_LIBC]: Fully reinstate the code that avoids the FD_SETSIZE limit
	by using poll instead.
	* resolv/res_comp.c: Likewise.
	[SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make dn_expand a
	weak alias for __dn_expand.
	* resolv/res_data.c: Likewise.
	(res_close) [_LIBC]: Don't call res_nclose if RES_INIT isn't set
	in _res.options.  Avoids a potential security risk by avoiding a
	close (0).
	[SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make
	res_mkquery, res_query, res_querydomain adn res_search weak
	aliases for __res_mkquery, __res_query, __res_querydomain and
	__res_search.
	* resolv/res_libc.c: (_res): Don't initialize.  Fix res_close
	instead to avoid close(0).
	(res_init): Always use the static resolver context.
	[SHLIB_COMPAT (libc, GLIBC_2.0, GLIBC_2_2)]: Make res_init a weak
	alias for __res_init.

	* resolv/resolv.h: Update from BIND 8.2.3-T5B.  Move definition of
	RES_SET_H_ERRNO and accompanying comment to...
	* include/resolv.h: ... here.

	* resolv/arpa/namser.h: Update from BIND 8.2.3-T5B.
	* resolv/arpa/nameser_compat.h: Likewise.
