add support to tag ipsec traffic belonging to specific IKE-initiated
phase 2 traffic. this allows policy-based filtering of encrypted and
unencrypted ipsec traffic with pf(4). see ipsec.conf(5) and
isakmpd.conf(5) for details and examples.
this is work in progress and still needs some testing and feedback,
but it is safe to put it in now.
