Update ospf6d to use new ibuf api.

This mostly moves away from memcpy(ibuf_seek(buf, off, size), data, size) to

Like ospfd allocate the recv buffer with malloc() on first call.
This code assumes some alignment of the buffer which may not be
the case with bss memory.

Like in ospfd use a static pkt_ptr buffer.

In recv_packet() verify that non-multicast packets where sent to the right
IPv6 address. Compare against all possible interface addresses instead of
only against iface->addr which is set to the last link-local address and
so there is a high chance of failure when multiple link-local addresses
are present.

Also simplify send_packet(), there is no need to use sendmsg() just use
sendto().

msg_controllen has to be CMSG_SPACE so that the kernel can account for
each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len). This
works now that kernel fd passing has been fixed to accept a bit of
sloppiness because of this ABI repair.

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.
norby@ agrees with the direction we're heading with this

remove log_debug() packet sending is now solid so no need to fill the log
with it.

Switch log_sockaddr() to take a void * so it is not necessary to cast the
sockaddr_in6 or sockaddr_in to a sockaddr.

send_packet() now takes a struct in6_addr as destination instead of a
struct sockaddr_in6 and builds the struct sockaddr_in6 internaly adding scope
if necessary. While there switch to sendto() we don't need any of the sendmsg()
features here.

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.

ok claudio@ dlg@

Delete superfluous #includes of <ifaddrs.h>, <net/if_dl.h>, and <net/if_enc.h>

ok krw@, jsg@

use the sizeof the struct not the sizeof a pointer to the struct
ok claudio@

Remove unnecessary netinet/in_systm.h include.

ok millert@

Passing MSG_DONTROUTE to sendto() here has no effect since SO_DONTROUTE
is only implemented for IPv4. Just remove it.

Tested by and ok florian@

Add missing #includes instead of assuming that some system header pulls in
the needed bits

ok deraadt@, millert@

Rename some imsg bits to make namespace collisions less likely buf to
ibuf, buf_read to ibuf_read, READ_BUF_SIZE to IBUF_READ_SIZE.

ok henning gilles claudio jacekm deraadt

msg_controllen has to be CMSG_SPACE so that the kernel can account for
each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len). This
works now that kernel fd passing has been fixed to accept a bit of
sloppiness because of this ABI repair.
lots of discussion with kettenis

Repair more msg_controllen dealing with structures or arrays of
descriptors; ok hshoexer, also looked at by kettenis and henning

Correct CMSG_SPACE and CMSG_LEN usage everywhere in the tree. Due to
an extensive discussion with otto, kettenis, millert, and hshoexer

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.
norby@ agrees with the direction we're heading with this

remove log_debug() packet sending is now solid so no need to fill the log
with it.

Switch log_sockaddr() to take a void * so it is not necessary to cast the
sockaddr_in6 or sockaddr_in to a sockaddr.

send_packet() now takes a struct in6_addr as destination instead of a
struct sockaddr_in6 and builds the struct sockaddr_in6 internaly adding scope
if necessary. While there switch to sendto() we don't need any of the sendmsg()
features here.
OK norby@

Remaining bit of last night work. Make packet reception use all the goodies
introduced (checksumming is no longer needed, no IP header checking is needed,
get a in6_pktinfo with the ifindex and dest addr, cleanup and remove a lot
of other code). With this ospf6d is able to send and receive first hello
packets. OK norby@
