99b71bbbd1 network: move service starts to tryStartServices
All of them only make sense on a fully synchronized node, doing anything
during the initial sync is just a waste of time.

f91ff78918 payload: drop Network from Extensible
It's only used to sign/verify it and is not a part of the structure. It's
still neded in consensus.Payload though because that's the way dbft library
is.

95c279325a block: drop Network from the Header
It's not network-tied any more, network is only needed to
sign/verify. Unfortunately we still have to keep network in consensus data
structures because of dbft library interface.

8444f3d816 network: refactor notary service's PostBlock
There was a deadlock while trying to finalize transaction during
PostBlock:
	1) (*Notary).PostBlock is called under the blockchain lock
	2) (*Notary).onTransaction is called inside the PostBlock
	3) (*Notary).onTransaction needs to RLock the blockchain to add
completed transaction to the memory pool (and the blockchain is Lock'ed
by this moment)

The problem is fixed by using notifications subsistem, because it's not
required to call (*Notary).PostBlock under the blockchain lock.

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.
