In the final RFC 5903 the computation for the DH shared secret changed.
Instead of the full point, only the X point is included.

The member g_xy is always the shared secret but so far its buffer has
been allocated using the size of the public points.  Since this is a
different size now, as the shared secret for EC Groups should only store
the x point, we need another member to specify the length of g_xy.

Since this is a backwards incompatible change older isakmpds won't be
able to negotiate if you use EC groups.  Bump the version of our own
vendor tag so peers can try to keep compatibility based on the presen-
ted tag.  This could be used to implement backwards compatibility to
older isakmpds.

Sync dh.[ch] from iked.  The files are identical, so any change in
either iked or isakmpd should be synced to the other daemon.  The
previous changes from iked include: plug two memory leaks, verify EC
points and add the Brainpool curves.  All tests in
regress/sbin/isakmpd/dh passed OKAY.

Replace the hand-crafted Diffie-Hellman implementation in isakmpd with
the smaller implementation from iked that is using libcrypto instead.
This allows to remove a lot of code (which is always good), get rid of
some custom crypto code by using libcrypto, theoretically adds
support for many new MODP and EC2N/ECP modes (but it is not configurable
yet), and allows to share the dh.c/dh.h code in different codebases
(it is identical in isakmpd and iked, but could also be used elsewhere).

partial move to KNF.  More to come.  This has happened because there
are a raft of source code auditors who are willing to help improve this
code only if this is done, and hey, isakmpd does need our standard
auditing process.  ok ho hshoexer

Initial import of isakmpd, an IKE (ISAKMP/Oakley) implementation for the
OpenBSD IPSEC stack by me, Niklas Hallqvist and Niels Provos, funded by
Ericsson Radio Systems.  It is not yet complete or usable in a real scenario
but the missing pieces will soon be there.  The early commit is for people
who wants early access and who are not afraid of looking at source.
isakmpd interops with Cisco, Timestep, SSH & Pluto (Linux FreeS/WAN) so
far, so it is not that incomplete.  It is really mostly configuration that
is lacking.
