9cf6cc61f4 network: allow multiple bind addresses for server
And replace Transporter.Address() with Transporter.HostPort() along the way.

23f118a1a9 network: rework discoverer/server interaction
* treat connected/handshaked peers separately in the discoverer, save
   "original" address for connected ones, it can be a name instead of IP and
   it's important to keep it to avoid reconnections
 * store name->IP mapping for seeds if and when they're connected to avoid
   reconnections
 * block seed if it's detected to be our own node (which is often the case for
   small private networks)
 * add an event for handshaked peers in the server, connected but
   non-handshaked ones are not really helpful for MinPeers or GetAddr logic

Fixes #2796.

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

0ba6b2a754 network: introduce peer sending queues
Two queues for high-priority and ordinary messages. Fixes #590. 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.

907a236285 network: move per-peer goroutines into the TCPPeer

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.

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.
