1526772663 network: drop requests to discovery pool when it can't be handled 
It happens from time to time in a four-node private network where there are
seeds (aka CNs) and not a lot of other nodes to connect to.

I don't know how to test for an infinite loop that has no side-effects, so no
test added here.

38a22b44b2 network: try connecting to seeds indefinitely, use them with 0 pool 
If the node is to start with seeds unavailable it will try connecting to each
of them three times, blacklist them and then sit forever waiting for
something. It's not a good behavior, it should always try connecting to seeds
if nothing else works.

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.

c8cc91eeee network: request blocks when there is a ping with bigger than ours height 
Turns out, C# node no longer broadcasts an Inv when it's creating a block,
instead it sends a ping and if we're not paying attention to the height
specified there we're technically missing a new block. Of course we'll get it
later after ping timer expiration and regular ping/pong sequence, but that's
delaying it for no good reason.

791c983304 core: drop GetScriptHashesForVerifying 
It no longer depends on blockchain state and there can't ever be an error, in
fact we can always iterate over signers, so copying these hashes doesn't make
much sense at all as well as sorting arrays in verifyTxWitnesses (witnesses
order must match signers order).

6c8accf18c core, network: request blocks instead of headers 
Closes #1192

1. We now have CMDGetBlockByIndex, so there's no need to request headers
   first when we can just ask for blocks.
2. We don't ask for headers (i.e. we don't send CMDGetHeaders),
   consequently, we shouldn't react on CMDHeaders.
3. But we still keep on reacting on CMDGetHeaders command as
   there could be a node which needs headers.

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.

b7dee156e2 network: fix a deadlock in DefaultDiscovery 
Why a deadlock can occur:
1. (*DefaultDiscovery).run() has a for loop over requestCh channel.
2. (*DefaultDiscovery).RequestRemote() send to this channel while
    holding a mutex.
3. (*DefaultDiscovery).RegisterBadAddr() tries to take mutex for write.
4. Second select-case can't take mutex for read because of (3).
