[HEADSUP] netgraph API/ABI changed

  Colleagues,

I've changed netgraph ABI between nodes and framework. API has been changed
a bit, too.

I haven't bumped NG_VERSION and NG_ABI_VERSION, since more changes may be
checked in.

If you tracking CURRENT and using netgraph, make sure to rebuild all
netgraph modules, if you've rebuilt netgraph.ko or kernel.
