eeeb0f6f0e core: accept two-side channels for sub/unsub, read on unsub
Blockchain's notificationDispatcher sends events to channels and these
channels must be read from. Unfortunately, regular service shutdown procedure
does unsubscription first (outside of the read loop) and only then drains the
channel. While it waits for unsubscription request to be accepted
notificationDispatcher can try pushing more data into the same channel which
will lead to a deadlock. Reading in the same method solves this, any number of
events can be pushed until unsub channel accepts the data.

260bcc0f49 wallet: fix wallet version to conform to NEP-6
See neo-project/neo#2390. Can't see it there? No wonder, that's why we have
this bug for a year and a half. Not critical, we don't care about versions,
but _very_ annoying.

9b0ea2c21b network/consensus: always process dBFT messages as high priority
Move category definition from consensus to payload, consensus service is the
one of its kind (HP), so network.Server can be adjusted accordingly.

5a7fa2d3df cli: restart consensus service on USR2
Fix #1949. Also drop wallet from the ServerConfig since it's not used in any
meaningful way after this change.

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

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).
