eca27055b8 core: fix NEP17 Transfer event 
`Transfer` event declaration was placed at the wrong part of
`newNEP17Native`, that's why it had incorrect parameters.

Fixed.

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
and
https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/NativeContract.cs#L148

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:
        	            	expected: 4
        	            	actual  : 3
        	Test:       	TestMempoolAddRemoveConflicts
```

Fixed by maling the nonce non-random.

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.

0b76f875c7 core: allow Null in System.Contract.Update 
Null means absense of script or manifest, empty
byte-slice is an error.

Related #1459.

eccf639803 core: add InitializeCache method to NEO native contracts 
There might be a case when cached contract values store nil (e.g.
after restoring chain from dump). We should always initialize cached
values irrespective to the (NEO).Initialize method.

This commit fixes a bug introduced in 83e94d3
when 4-nodes privnet is failing after restoring from dump:
```

af6a6f5f30 consensus: fix potential system deadlock 
There is a notification pushed into the channel when block is being added,
that notification is read by special goroutine that then forwards it to all
subscribers to that particular event. Consensus goroutine is one of that
subscribers, so for the system to properly function it has to read these
events, but at the same time it can generate new blocks inside, so in some
cases it can generate two blocks without ever reading from the subscription
channel and this will lead to a deadlock.

To avoid that we need to check subscription channel for events on every loop.

33ea179f6e core: remove forward index check from addHeaders() 
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.
