While optimizing jumps, old offsets should be compared
with the method offset before optimization, not with
the constantly changing value.

f8d5c40928 compiler: do not DROP return value with type assertion 
The same problem as with IF. Example:

```
func foo() interface{} {
    ...
}

func Main() int{} {
   return foo().(int)    <--- panic here
}
```

dbce3c9a19 compiler: do not DROP unary expression value inside IF stmt 
We dropped values from such calls because they where marked as unused
(consequently, were followed by DROP instructions). Example:

if !foo() {    <--- panic here
    ...
}

This commit prevents the following runtime error during script execution:
```
"error encountered at instruction ** (NOT): runtime error: invalid memory address or nil pointer dereference"

```

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).

38a22b44b2 network: try connecting to seeds indefinitely, use them with 0 pool 
If the node is to start with seeds unavailable it will try connecting to each
of them three times, blacklist them and then sit forever waiting for
something. It's not a good behavior, it should always try connecting to seeds
if nothing else works.

097ef2a731 core: copy storage item key in simple.GetStorageItems 
Related to #1468, ported from #1475.

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.

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:

e0f406fd3a rpc/client: add constant to ValidUntilBlock 
There are 2 problems:
1. `getvalidators` RPC can return empty list.
2. `+1` in single node can be too resrictive.
Proper solution for (1) may require requesting
standby validators. Here we add constant
to fix occasional test failures.

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.

Inspired by neo-project/neo-vm#352. We can't directly compare slices, so we're
better optimize things we already have. At the same time this code would
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%.

bcb7b9ba63 smartcontract: rename parameter ByteString to ByteArray 
Debugger expects it to be ByteArray. C# compiler also compiles it
as `ByteArray` (in both manifest and debug.json).

The previous commit 6a2161207a changed
this line as C# implementation serializes Blockchain.ApplicationExecuted.Stack
as array of stackitem.Item and deserializes it as array of
smartcontract.Parameter.
