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.

0d8cc437fe mempool: swap checks in Add, fail fast

c7032022f8 core: don't search through the whole DAO in isTxStillRelevant 
New transactions are added to the chain with blocks. If there is no
transaction X at height N in DAO, it could only be added with block N+1, so
it has to be present there. Therefore we can replace `dao.HasTransaction()`
check with a search through in-block transactions. HasTransaction() is nasty
in that it may add useless load the DB and this code is being run with a big
Blockchain lock held, so we don't want to be delayed here at all.

Improves single-node TPS by ~2%.

3a379e4f3e core: don't reverify mempooled transactions in AddBlock 
The end effect is almost as if `VerifyTransactions: false` was set in the
config, but without actually compromising the guarantees provided by it.

It almost doubles performance for single-mode benchmarks and makes block
processing smoother (more smaller blocks are being produced).

591f639ad6 core: fix getOnPersistWrapper for native contracts 
According to manifest, OnPersist.ReturnType is void, so we shouldn't
return anything from it. It's not so important, as we drop this value at
the end of OnPersist invocation.

d0c29f52c9 core: verification script must return exactly one value 
C# node is quite picky as it expects there to be exactly one value returned,
but our testchain actually adds 4 signatures for multisig cases instead of 3
which makes it technically incompatible with C# node.
