Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

Remove private CVS tag from an obsolete repository and bump copyright
to 2013 while I'm here... this is my way of saying "happy new year!".

Include the license and copyright notice in the generated files.

Move the arrays of default IKE and ESP transforms into parse.y instead
of generating them with genmap from ikev2.h. They're only really
needed in parse.y and this diff also allows to simplify genmap.sh.

update email addresses to match reality.

fixup formatting in the generated files

Import iked, a new implementation of the IKEv2 protocol.

iked(8) is an automatic keying daemon for IPsec, like isakmpd(8), that
IPsec creates flows and SAs automatically. Unlike isakmpd, iked(8)
implements the newer IKEv2 protocol instead of IKEv1/ISAKMP. The
daemon is still work-in-progress and not enabled in the builds, but is
already able to establish IKEv2 sessions with some other IKEv2
implementations as a responder.

with lots of help and debugging by jsg@
