	* irdp.h: Add prototype for irdp_sock_init, and fix protos for
	  other irdp_* functions.
	* irdp_interface.c: (irdp_if_start) If irdp_sock is negative,
	  call irdp_sock_init to create the IRDP socket.
	  (irdp_if_init) Rename to irdp_init().
	  (get_iflist_ifp) Remove function that is a duplicate of
	  if_lookup_by_index.
	  (*) Make many functions static.  And remove superfluous "\n" from
	  several zlog messages.
	* irdp_main.c: (irdp_init) Remove function that used to call
	  irdp_if_init() and irdp_sock_init(), since we will now create
	  the socket only upon first use.
	  (irdp_sock_init) Do not update global irdp_sock variable, just
	  return the fd and assume that the caller will do so.  If setsockopt
	  calls fail, close the socket before returning -1.
	  (*) Make many functions static.
	* irdp_packet.c: Initialize irdp_sock to -1.
	  (irdp_read_raw) Call standard library function if_lookup_by_index
	  instead of get_iflist_ifp.
	  (irdp_recvmsg) Should be static, not global.
