This makes sure the event is only triggered after the IKE_SA is fully
established and e.g. virtual IPs, additional peer addresses or
a modified reauth time (on the initiator) are assigned to it. This was
e.g. a problem for the selinux plugin if virtual IPs are used.
We use a separate task to trigger the event that's queued before the
child-create task so the event is triggered before the child_updown()
event. Same goes for the state change to IKE_ESTABLISHED.
A new condition is used to indicate the successful completion of all
authentication rounds, so we don't have to set the IKE_ESTABLISHED state
in the ike-auth task (it was used as condition in other tasks).
Since set_state() also sets the rekey and reauth times, this required
some minor changes in regards to how AUTH_LIFETIME notifies are handled.
For documentation purposes the new folders ikev1-algs, ikev2-algs,
ikev1-multi-ca and ikev2-multi-ca have been created. Most of the
test cases have now been converted to the vici interface. The
remaining legacy stroke scenarios yet to be converted have been put
into the ikev2-stroke-bye folder.
For documentation purposes some legacy stroke scenarios will be kept
in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.
The main difference is that ping now reports icmp_seq instead of
icmp_req, so we match for icmp_.eq, which works with both releases.
tcpdump now also reports port 4500 as ipsec-nat-t.
