Ulrich Drepper 2bbb7d5b3c * resolv/res_init.c (res_setoptions): Recognize edns0 option.
* resolv/res_mkquery.c: Define __res_nopt.
	* resolv/res_query.c (__libc_res_nquery): If RES_USE_EDNS0 is set
	try adding EDNS0 record.
	* resolv/res_send.c (send_dg): If request failed with FORMERR and
	EDNS0 record was send make sure we don't try it again.
	* resolv/resolv.h: Define RES_F_EDNS0ERR and RES_USE_EDNS0.
	* include/resolv.h: Declare __res_nopt.
