2290b91b83 core: fix verification call flag 
Previous commit sets AllowCall flag as required for Neo.Native.Call, but
invocation script was loaded with ReadStates flag => native contracts
verification failed.

Other contracts can also make use of AllowCall call flag.

2ab0e6c399 core: check stack length before returning false verification result 
We must be sure that stack has no other items before returning `false`
verification result. It is an error in both cases, but by preserving the
order we know exactly that it was correct `false` on stack.

b7e86fa6a3 manifest: add Safe flag to method descriptor 
`interop.Contex.AddMethod` sets `Safe` flag for native
contracts. This allows not to forget to change manifest
when changing call flags.
Also fixed invalid `Safe` flags for `Notary` and `Designate` contracts.

d93aa745bb contract: avoid going to the DB for entry scripts 
This optimizes out DB access for non-deployed contracts under the assumption
that deployed ones are always loaded via `LoadScriptWithHash` (and if they're
not --- it's a bug anyway with the new hashing model) which actually is a very
popular case (every entry script does that).

2fee69f26f core: add missing onPersist and postPersist methods to natives 
Although not every contract is persisted (see
https://github.com/neo-project/neo/blob/master/src/neo/Ledger/Blockchain.cs#L94)
we have to add `onPersist` and `postPersist` methods to every
native contract in order to display them in manifest for users and
follow C# behaviour. In C# there are `onPersist` and `postPersist`
methods in base native contract class, see
https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/NativeContract.cs#L141

54e6bcad12 core: fix failing mempool test 
There might be a case when identical nonces are generated for tx6, tx7 or
tx8 (they are not in mempool, so each of them pass mempool-presence
check). In this case test fails due to the lack of hashes into mp.conflicts
map (two of tx6, tx7 or tx8 have identical hashes) with the following
error:

```
=== RUN   TestMempoolAddRemoveConflicts
--- FAIL: TestMempoolAddRemoveConflicts (0.00s)
    mem_pool_test.go:376:
        	Error Trace:	mem_pool_test.go:376
        	Error:      	Not equal:

        	            	actual  : 3

0232bbcb0c core: refactor GASRecord handling 
We should store each GAS record as
{
    Key: ContractID + RecordsPrefix + RecordID,
    Value: RecordValue,
}
So don't use state.GASRecord for storing anymore. However, it's still
useful to cache GasRecord values by using state.GASRecords, because we
have to keep GASIndexPairs sorted by indexes.

fe1f0a7245 core: introduce CheckReturnState constants 
At the moment we should have 3 possible options to check return state
during vm context unloading:
	* no check
	* ensure the stack is empty
	* ensure the stack is not empty

It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

We should copy the key to avoid bytes substitution. Otherwise there's a
chance that at the end of dao.Store.Seek(...) execution some keys won't
be the same as the original keys found inside saveToMap function because
storage.Seek can guarantee that provided key and value are only valid
until the next `f` call.

when 4-nodes privnet is failing after restoring from dump:

It can't ever happen. We're guaranteed to have a consistent chain of headers
(we're verifying them above, if we're not verifying --- it's not our fault)
that starts at HeaderHeight that was actual when we were asking for it
previously. HeaderHeight can only move forward, so if that happened that would
be filtered out by the condition below and the first one can't happen. Though
to be absolutely sure change the second check to only pass "+1" headers (which
is what we want).

ce09c82b25 block: remove Verify() 
It's used in two places now:
 * Blockchain.AddBlock()
   This one does transaction duplication check of its own, doing it in
   Verify() is just a waste of time. Merkle tree root hash value check is
   still relevant though
 * Block.DecodeBinary()
   We're decoding blocks for the following purposes:
     - on restore from dump
       The block will be added to the chain via AddBlock() and that will do a
       full check of it (if configured to do so)
     - on retrieving the block from the DB (DAO)
       We trust the DB, if it's gone wild, this check won't really help
     - on receiving the block via P2P
       It's gonna be put into block queue and then end up in AddBlock() which
       will check it
     - on receiving the block via RPC (submitblock)
       It is to be passed into AddBlock()
     - on receiving the block via RPC in a client
       That's the only problematic case probably, but RPC client has to trust
       the server and it can check for the signature if it really
       cares. Or a separate in-client check might be added.

As we can see nothing really requires this verification to be done the way it
is now, AddBlock can just have a Merkle check and DecodeBinary can do fine
without it at all.

9591d64e53 mempool: don't sort items by hash 
There is nothing requiring us to do so. It also is bad because it allows for
new transaction to replace some already existing one with the same fee
parameters just because it has "better" hash.

But the other thing is that for transactions with equal fees it's always
better for us to append them to the end of the list, instead of inserting them
in the middle, so this change allows to reduce slice item movements and gain
some 6-7% increase for single-node TPS.

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.

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%.

7c6cdcbcc9 core: fix bug with policy.MaxVerificationGas 
In 121c9664b we should take into account isValid flag of
NativePolicy contract while retrieving MaxVerificationGas native
policy value. Otherwise we won't be able to get MaxVerificationGas
after the node was restarted, because this value is not truly
stored along with the other native policy values.

This commit fixes bug with headers verification after the  node
restarting with an existing storage:

236438d799 core: do MPT compaction every once in a while 
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
