* resolv/res_init.c (__res_iclose): New function. Broken out of

	res_nclose.  Take addition parameter which determines whether
	addresses should be freed.
	(res_nclose): Call __res_iclose.
	(res_thread_freeres): Likewise.
	* resolv/res_data.c (res_close): Call __res_iclose.
	* resolv/res_libc.c (res_init): No need to separately free the
	addresses.
	(__res_maybe_init): Likewise.
	* resolv/res_send.c: Use __res_iclose instead of res_nclose.
	* resolv/Versions [GLIBC_PRIVATE]: Add __res_iclose.
	* include/resolv.h: Declare __res_iclose.
	Add libc_hidden_proto for __res_iclose.
	* hesiod/hesiod.c (__hesiod_res_set): No need to free name server
	addresses here again.
