9eafec0d1d network: introduce peer-to-peer message queue
This one is designed to give more priority to direct nodes communication, that
is that their messaging would have more priority than generic broadcasts. It
should improve consensus process under TX pressure and allow to handle
pings in time (preventing disconnects).

06c3fbe455 network: rework ping sends, fix overpinging
Our node was too pingy because of wrong timer setups (that divided timeout
Duration by time.Second), it also was wrong in its time calculations (using
UTC time to calculate intervals). At the same time missing block is a
server-wide problem, so it's better solved with server-wide protocol loop.

1f672e0da7 network: move SendVersion() to the Peer
Only leave server-specific `getVersionMsg()` in the Server, all the other
logic is peer-related.

2c4ace022e network/config: redesign ping timeout handling a bit
1) Make timeout a timeout, don't do magic ping counts.
2) Drop additional timer from the main peer's protocol loop, create it
   dynamically and make it disconnect the peer.
3) Don't expose the ping counter to the outside, handle more logic inside the
   Peer.

0ba6b2a754 network: introduce peer sending queues
Two queues for high-priority and ordinary messages. Fixes . These queues
are deliberately made small to avoid buffer bloat problem, there is gonna be
another queueing layer above them to compensate for that. The queues are
designed to be synchronous in enqueueing, async capabilities are to be added
layer above later.

4e6ed9021c network: add ping pong processing
add pingInterval same as used in ref C# implementation with the same logic
add pingTimeout which is used to check whether pong received. If not -- drop the peer.
add pingLimit which is hardcoded to 4 in TCPPeer. It's limit for unsuccessful ping/pong calls (where pong wasn't received in pingTimeout interval)

I think it's useless, buggy and hides parsing errors for no good reason.
