* malloc/thread-freeres.c: Conditionalize on _LIBC_REENTRANT.
* sunrpc/rpc_thread.c: Likewise for text_set_element use.
(__rpc_thread_destroy): Add it to __libc_subfreeres too.
* include/resolv.h: Add libc_hidden_proto for __res_nclose.
* resolv/res_init.c (__res_nclose): Add libc_hidden_def.
(res_thread_freeres): New function, on __libc_thread_subfreeres and
__libc_subfreeres.
* malloc/Versions (libc: GLIBC_PRIVATE): Add __libc_thread_freeres.
* sunrpc/Versions (libc: GLIBC_PRIVATE): Removed.
