* 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.
