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.

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.

core: refactor and improve verification and pooling
...
Now we have VerifyTx() and PoolTx() APIs that either verify transaction in
isolation or verify it against the mempool (either the primary one or the one
given) and then add it there. There is no possibility to check against the
mempool, but not add a transaction to it, but I doubt we really need it.
It allows to remove some duplication between old PoolTx and verifyTx where
they both tried to check transaction against mempool (verifying first and then
adding it). It also saves us utility token balance check because it's done by
the mempool anyway and we no longer need to do that explicitly in verifyTx.
It makes AddBlock() and verifyBlock() transaction's checks more correct,
because previously they could miss that even though sender S has enough
balance to pay for A, B or C, he can't pay for all of them.
Caveats:
* consensus is running concurrently to other processes, so things could
change while verifyBlock() is iterating over transactions, this will be
mitigated in subsequent commits
Improves TPS value for single node by at least 11%.

network: add a nil check in (*TCPTransport).Close, prevent panic
...
You have to try to trigger that, but in the event of server shutdown before it
actually started listening Close will easily panic like this:
2020-03-05T11:48:08.660+0300 INFO node started {"blockHeight": 6458, "headerHeight": 15605}
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x9d5f0a]

network: rework shutdown sequence of Server
...
Close transport and disconnect peers right in the Shutdown(), so that no new
connections would be accepted and so that all the peers would be disconnected
correctly (avoiding the same deadlock as in e2116e4c3f
).

(*Peer).Disconnect send an unregister signal to this goroutine, so invoking it
