* sunrpc/svcauth_des.c (cache_init): Use calloc instead of
	malloc&bzero.

	* sunrpc/svc_udp.c (BZERO): Remove definition.
	(CALLOC): Define.
	(svc_enablecache): Use CALLOC instead of ALLOC&BZERO.

	* sunrpc/des_impl.c: Remove ALT_ECB support.  We never used it.
	(des_SPtrans): Use uint32_t type.
	(des_skb): Likewise.

	* sunrpc/xdr_ref.c (xdr_reference): Use calloc instead of malloc&bzero.

	place where the iso639 array might be accessed beyond the limits.
