Update ospf6d 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().

log the interface along with the neighbour ID in various ospfd/ospf6d
messages. ok remi@ benno@

if a neighbour is reachable over multiple network links, some problems
may be related to the link itself rather than the neighbour, so knowing
the interface can be important when trying to locate the source of a
problem.

When calculating how much payload ospf6d can put into DD and LSREQ packets
substract the size of the IPv6 header and not the IPv4 header from the MTU.
This stops ospf6d to send out fragmented packets

Monster commit of stuff I did mostly last month. What it does:
* removes kif and uses iface for everything interface related.
This removes unneeded data redundancy which makes the code more complex.
* adds the link local prefix to struct iface and attaches a list with
the other prefixes to the struct iface. This is needed to generate the
link LSA.
* disconnects struct iface from struct area (the backpointer is gone)
this will make the reload code a bit easier.

area_ospf_options() should return the options in network byte order.

From ospfd:
Bye bye global ospf options. OSPF options are per area (at least the one
flag that we set). So introduce a area_ospf_options() function that will

From ospfd:
Bye bye global ospf options. OSPF options are per area (at least the one
flag that we set). So introduce a area_ospf_options() function that will
return the correct flags for each area. This makes stub area support a lot
easier.
Don't check for OSPF_OPTION_E in the parent. OSPF_OPTION_E is per area and
so the parent process has no way to know if it should redistribute or not.

Do not overload nbr->options with the dd exchange bits. nbr->options is used
by the hello protocol. Instead add a dd_more flag that is used together with

Welcome ospf6d

The new ospf6d daemon will support OSPFv3, basically OSPF for IPv6 networks.

It is heavily based on ospfd(8), it is more or less a copy and paste of it.
Currently some unneeded stuff

Welcome ospf6d

The new ospf6d daemon will support OSPFv3, basically OSPF for IPv6 networks.

It is heavily based on ospfd(8), it is more or less a copy and paste of it.
Currently some unneeded stuff has been removed and the trasition from
IPv4 to IPv6 has begun.

ospf6d is not very usefull at the moment, it is being imported to allow more
people to work on it concurrently.

Not yet connected to the builds.
