* 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.
