4d286dcfeb network: check height before requesting headers 
Only request headers from the other peer if his height is bigger than
ours. Otherwise we routinely ask 0-height newcomers for some random headers

9f9cf4ae3f network: add getheaders message processing 
This one is essential for the consensus nodes as otherwise they won't give out

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).

Merge pull request #476 from nspcc-dev/feature/neoUT 
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.
