b05754deac core: add Close() to blockchainer, implement it to properly close chain
Before it the deferred function in Run() was actually never able to properly
close the Store, so we weren't synching the latest state to the disk.

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.

d7f747fa9a network: wait for both Version messages before ACKing
Otherwise the node might crash in `startProtocol` because of missing Version
field in the peer. And it also keeps the sequence correct, Version MUST be
sent first and ACKs can only follow it.

c16c2bf102 core: store current header reference on clean init
Missing it the following line could fail on subsequent restarts:

        currHeaderHeight, currHeaderHash, err := storage.CurrentHeaderHeight(bc.store)

if the node was stopped before any headers had been received.

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.

b46dd295bc rpc: add CORS workaround for RPC
This one enables our RPC to be called from the browser if there is a
need. It's insecure and not standards-compliant, thus this behaviour is
configurable is not enabled by default. It makes our node with this workaround
enabled compatible with neo-mon monitoring.

Originally debugged by @anatoly-bogatyrev in #464.
