	* ospfd.h: Add new field struct stream *ibuf to struct ospf.
	* ospfd.c: (ospf_new) Check return code from ospf_sock_init.
	  Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1).
	  (ospf_finish) Call stream_free(ospf->ibuf.
	* ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then
	  pass it to ospf_recv_packet for use in receiving the packet
	  (instead of allocating a new stream for each packet received).
	  Eliminate all calls to stream_free(ibuf).
	  (ospf_recv_packet) The struct stream *ibuf is now passed in as
	  an argument.  No need to use recvfrom to peek at the packet
	  header (to see how big it is), just use ospf->ibuf which is
	  always large enough (this eliminates a system call to recvfrom).
	  Therefore, no need to allocate a stream just for this packet,
	  and no need to free it when done.
