Punt Infra
A punt/exception path that provides:
1) clients that use the infra
2) clients can create punt reasons
3) clients can register to recieve packets that are punted
for a given reason to be sent to the desired node.
4) nodes which punt packets fill in the {reason,protocol} of the
buffere (in the meta-data) and send to the new node "punt-dispatch"
5) punt-dispatch sends packets to the registered nodes or drops
