a87b8578b2 network: stub "StateService" payloads out for now 
And stop dropping connections if we're to receive them. Proper handling is
subject of #1701, but we need at least some connection-level stability for
now.

686f983ccf network: prevent disconnects during initial sync 
Node receiving extensible payload from the future is confused and drops
connection. Note that this can still happen if the node is to loose its
synchrony.

Calling `IsInSync()` is quite expensive, so we stop doing that once synchrony
is reached (hence bool flag).

43e4d3af88 oracle: integrate module in core and RPC 
1. Initialization is performed via `Blockchain` methods.
2. Native Oracle contract updates list of oracle nodes
  and in-fly requests in `PostPersist`.
3. RPC uses Oracle module directly.

163d90c866 network: don't register addresses before version handshake 
1) It duplicates registration in `version` message handler and no valid
   connection can work without version exchange.
2) On public networks we have seed nodes defined by names, so we register
   connections to them using these names, but then if connection is dropped we
   delist them by IP:PORT combinations which can lead to zero PeerCount() with
   all seeds still being registered as connected in the discovery subsystem
   and thus no reconnection attempts being made.

5bd6c1e5cc network: fix a bug in discovery with a peer connected twice 
It could be the case that checks are performed simultaneosly and
peers connections goes down from 2 to 0. We must take such case into
account and register address as good in discovery.

0a5049658f network: support non-blocking broadcast 
Right now a single slow peer can slow down whole network.
Do broadcast in 2 parts:
1. Perform non-blocking send to all peers if possible.
2. Perform blocking sends until message is sent to 2/3 of good peers.

1526772663 network: drop requests to discovery pool when it can't be handled 
It happens from time to time in a four-node private network where there are
seeds (aka CNs) and not a lot of other nodes to connect to.

I don't know how to test for an infinite loop that has no side-effects, so no
test added here.

38a22b44b2 network: try connecting to seeds indefinitely, use them with 0 pool 
If the node is to start with seeds unavailable it will try connecting to each
of them three times, blacklist them and then sit forever waiting for
something. It's not a good behavior, it should always try connecting to seeds
if nothing else works.
