43bfc909eb consensus: flush previous proposal on new block
Reusing proposals from previous blocks doesn't make sense. And reduce some
code duplication along the way.

8c0a7225e5 consensus: only use previous proposal if it has something in it
It might just be uninitialized it doesn't really make sense using zero-length
previous proposal anyway.

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.

55b2cbb74d 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%.

Fixes #667, fixes #668.

0bf2fa915e consensus: don't decrypt the key again and again, cache it
It's cached in dbft for a view anyway, so there is no big difference here
from security POV. Lets us squeeze yet another 4% TPS improvement.

Make the system fail if unable to decrypt the key along the way, which is a
part of #1312.

a46c71f2de consensus: prevent synchronization stalls
When CN is not up to date with the network is synchonizes blocks first and
only then starts consensus process. But while synchronizing it receives
consensus payloads and tries to process them even though messages reader
routine is not started yet. This leads to lots of goroutines waiting to send
their messages:

Luckily it doesn't break synchronization completely as eventually connection
timers fire, the node breaks all connections, create new ones and these new
ones request blocks successfully until another consensus payload stalls them
too. In the end the node reaches synchronization, message processing loop
starts and releases all of these waiting goroutines, but it's better for us to
avoid this happening at all.

This also makes double-starting a no-op which is a nice property.

8de0332107 *: use MaxTransactionsPerBlock from Policy native contract
part of #904

1. We now have MaxTransactionsPerBlock set in native Policy contract,
   so this value should be used in (dbft).GetVerified method instead
   of passing it as an argument.
2. Removed (dbft).WithTxPerBlock.
2. DBFT API has changed, so update it's version.
3. Removed MaxTransactionsPerBlock from node configuration, as we
   have it set in native Policy contract.

b483c38593 block/transaction: add network magic into the hash
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.

462022bbdd consensus: remove OnNewBlock(), use Blockchain subscription
Get new blocks directly from the Blockchain. It may lead to some duplications
(as we'll also receive our own blocks), but at the same time it's more
correct, because technically we can also get blocks via other means besides
network server like RPC (submitblock call). And it simplifies network server
at the same time.
