6701e8cda0 compiler: allow to use local variables in init() 
Because body of multiple `init()` functions constitute single
method in contract, we initialize slot with maximum amount of
locals encounterered in any of `init()` functions and clear them
before emitting body of each instance of `init()`.

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

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.

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.

behave a bit different if A is to call B and then B is call A and then some
pointer from the first A invocation is to be compared with a pointer from the
second A invocation. Not sure it really matters.

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%.

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.

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.
