BEP42: Pick node ID based on external IP (DHT security extension)

[feross]

We have been looking at securing the DHT, making it harder to attack (especially with sybils). One thing we’re implementing to support this is requiring DHT nodes to calculate their node ID based on their external IP, with some flexibility to support NATs and such. More info on Node ID enforcement can be found here.
