138e125646 *: remove duplicate functions producing verification script 
Drop wif.GetVerificationScript(), drop
smartcontract.CreateSignatureRedeemScript(), add GetVerificationScript()
directly to the PublicKey and use it everywhere.

8d4dd2d2e1 vm: move opcodes into their own package 
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

The problem is that we're modifying `unsortedTxn` under a reader lock.

734338ad70 network: move Version sending to the tcp transport 
We have a race between reader and writer goroutines for the same connection
that leads to handshake failures when reader is faster to read the incoming
version (and try to reply to it) than writer is to write our own Version:

WARN[0000] peer disconnected                             addr="172.200.0.4:20334" peerCount=5 reason="invalid handshake: tried to send VersionAck, but didn't send Version yet

Fix it by moving Version sending before the reader loop starts.

467c9c146d core: restore intermediate block-level store 
Commit c80ee952a1 removed temporary store used
to contain changes of the block being processed. It's wrong in that the block
changes should be applied to the database in a single transaction so that
there wouldn't be any intermediate state observed from the outside (which is
possible now). Also, this made changes commiting persist them to the
underlying store effectively making our persist loop a no-op (and not
producing `persist completed` log lines that we love so much).

e3098ed0f8 network: write messages atomically 
Right now message can be written in several Write's so

c567307748 core: fix potential issue with header list init 
If we're to receive some 500 headers (less than `headerBatchCount`) and quit
before receiving more of them we end up with clean `bc.headerList` that will
be inited going backwards to the `targetHash`, but code path doesn't add add
the `targetHash` itself which it should do in this particular case, otherwise
we end with no genesis block hash in the list.

VM: Use JSON-based tests from neoVM

After the implementation of stack limits nothing is needed for us to pass reference JSON tests :)
The only thing that differs --- we do not compare stack in case of FAULT (which matches NEO 3 behavior).
Also two commits were reverted to match 2.x VM behavior.

7cf9a40468 network: fix MaxPeers, introduce AttemptConnPeers 
Our node didn't respect the MaxPeers setting, fix it with a drop of random
connection when this limit is reached (to give a chance for newcomers to
communicate), but also introduce AttemptConnPeers setting to tune the number
of attempted connections.

This also raises the default MaxPeers for testnet/mainnet to 100, because
neo-go nodes love making friends.

ec76ed23a5 network: rework peer handshaking, fix #458 
This allows to start handshaking from both client and server (mainnet/testnet
nodes were seen to not care about string ordering for it), but still maintains
some sane checks in the process. It also makes functions thread-safe because
we have two goroutines servicing read and write side of the Peer connection,
so they can clash on access to the struct fields.

Add a test for it also.

de2eeb4671 rpc: add one to the block height for the getblockcount response 
There is a difference in interpretation of what a block count is. neo-go nodes
currently respond to this request with the latest block number which is the
same number that neoscan.io shows. However, C# nodes deliberately do add one
to this number when answering to the getblockcount request to account for the
genesis block number 0.

This patch makes us consistent with C# nodes wrt to getblockcount behaviour.
