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.

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.

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.

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.

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.
