* 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.
