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.

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).

db65ed04d9 consensus: apply policy during verifyBlock
To follow C# implementation we should also check proposed block on
policy matching.

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.

taking into account decimals.

e5f05790d5 core: cache standby validators in the Blockchain
They never change, so it makes no sense parsing the keys over and over
again. It also simplifies the interface a little.

You no longer can transfer them, so creating/renewing/storing doesn't make
much sense.
