Neale Ranns 8d6d74cdf4 vlib: Punt reason allocation listener enable/disable callback
Type: improvement

allow clients that allocate punt reasons to pass a callback function
that is invoked when the first/last client registers to use/listen on
that punt reason. This allows the client to perform some necessary
configs that might not otherwise be enabled.
IPSec uses this callback to register the ESP proto and UDP handling
nodes, that would not otherwise be enabled unless a tunnel was present.

Neale Ranns 50f0ac0f09 Punt: socket register for exception dispatched/punted packets based on reason
- add to the Punt API to allow different descriptions of the desired packets: UDP or exceptions
- move the punt nodes into punt_node.c
- improve tests (test that the correct packets are punted to the registered socket)

Neale Ranns 76b5649d07 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
