88542630ac blockchainer: drop the package completely
It's not an ideal solution, but at least it solves the problem for
now. Caveats:
 * consensus only needs one method, so it's mirrored to Blockchain
 * rpcsrv uses core.* definition of the StateRoot (so technically it might as
   well not have an internal Ledger), but it uses core already unfortunately

no need to close it manually. Introduced in #2184.

de203b5c76 consensus: check whether server is started before transaction handling
consensus.OnTransaction is a callback, so it can be called at any time.
We need to check whether service (and dBFT) is started before the
subsequent transaction handling like it is done inside the OnPayload
callback.

66aafd868b network: unplug stateroot service from the Server
Notice that it makes the node accept Extensible payloads with any category
which is the same way C# node works. We're trusting Extensible senders,
improper payloads are harmless until they DoS the network, but we have some
protections against that too (and spamming with proper category doesn't differ
a lot).

need to use it here.

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

af6a6f5f30 consensus: fix potential system deadlock
There is a notification pushed into the channel when block is being added,
that notification is read by special goroutine that then forwards it to all
subscribers to that particular event. Consensus goroutine is one of that
subscribers, so for the system to properly function it has to read these
events, but at the same time it can generate new blocks inside, so in some
cases it can generate two blocks without ever reading from the subscription
channel and this will lead to a deadlock.

To avoid that we need to check subscription channel for events on every loop.
