Update ospfd to use new ibuf api. This mostly moves away from memcpy(ibuf_seek(buf, off, size), data, size) to ibuf_set(buf, off, data, size). Also ibuf_reserve() is replaced with ibuf_add_zero(). OK tb@

Rework the LSA cache and make it behave. Until now we only used the type, id and adv router as hash and that resulted and weird behaviour. Because the age was not used in the compare it was almost impossible to MAXAGE some LSAs in busy networks. The result was a slowly growing retransmission queue and an ospf engine spending way to much time traversing these sometimes huge queues. Now we just hash the full lsa_hdr and so age is included. Additionally correctly age LSAs in the retransmission queues. ok ok ok ok ok ok and a lot of help (plus a busy OSPF network) norby@

Fix a memory leak in the ospf engine. First of all ospfd did not track if a LSA was already queued on nbr self. So after the first round -- where the lsa was queued -- ospfd would remove it again in a second run. That was not enough but the LSA was removed from the wrong neighbor -- nbr instead of iface->self. LIST_REMOVE does not track the queue and so that resulted in some strangeness (especially the lsa_cache did not get cleared). OK norby@

Welcome ospfd started by Esben Norby some time ago by using the imsg/three process framework of bgpd. He implemented the basic concept plus the ospf finite state machines. Later I joined and helped him cleanup, debug and extend his work. Right now it is not particularly useful, major parts are still missing but is imported to allow more people to work on it. status: The basic protocol works for broadcast networks and the LS database is synchronized and updated. It is not possible to be DR or BDR on a network and other interface types like point-to-point are not yet supported. The shortest path tree is not calculated and so no routing information is exchanged with the kernel FIB. Not yet connected to the builds. OK henning@
