RFC: IPSEC patch 0 for netlink events

[jamal <hadi@xxxxxxxxxx>]

Folks,

first patch that changes internal api slightly to allow for next
patch which will add other events. It includes the other acquire patch i
posted earlier - please ignore that - Or if you like this patch use it
instead.
This patch also adds a few new groups.

I am dependent on this before going to next steps so please comment
if you can - the patch is very small

cheers,
jamal
