e4b52d3947 core/rpc: add continue flag to iterating functions 
Most of the time we don't need to get all transfers from the DB and
deserialize them.

7e34072519 core: implement (*Blockchain).VerifyWitness 
`ScriptFromWitness` is no longer useful, because we support
contract verification.

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.

807338f97e core: do not store NEP5 transfer log in memory 
Traversing transfer log instead of accumulating and returning it
is faster and takes less memory.

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).

7eef895061 consensus: use GetNextBlockValidators where appropriate 
GetValidators without parameter is called upon DBFT initialization and it
should receive validators for the next block (that will create it),
parameterized GetValidators is used for NextConsensus calculation where we
need a list for the current state of the chain.

There is no such thing as high/low priority transactions, as there are
no free transactions anymore and they are ordered by fees contained
in transaction itself.
