Note that the code can be greatly simplified by having the network immediately start when we create the service, and by passing a list of protocols to the constructor instead of registering them afterwards. I will only do these changes after this PR has been merged, in order to not introduce merge conflicts. |

I've been asked to use a branch in the local repo instead, so re-opening as #268 |

Close #187
Removes the
ethcore-network-devp2pcrate and integrates a newsubstrate-libp2pcrate.The API of this crate is exactly the same as devp2p, so the replacement is quite straight-forward.
Once this is merged I would like to refactor a bit the networking API in order to make it less error-prone.
What the code does on the wire is it performs a random Kademlia
FIND_NODErequest every 30 seconds, and tries to open the/substrate/dot/0protocol with each of the resulting nodes (until we reachmin_peers, after which it only listens to connections).Consequently, in practice the bootstrap nodes should be used only for Kademlia and not for substrate/dot, unless there are not enough nodes available.
The format of a peer address in libp2p is not
enode://...@..., but/ip4/1.2.3.4/tcp/10000/p2p/Qm...(or/ip6/::1/tcp/10000/p2p/Qm...) where theQmpart is the base56 encoding of a peer ID.NAT traversal "works" in the sense that nodes have knowledge of their external IP and report it. However there is no such thing as UDP hole punching implemented yet.
I will continue to push commits on this branch in order to improve readability and reliability, but you can can start playing with it if you want. Since the change surface is really low, it should be easily rebasable on any other branch.
