f60b9059e4 net: Pass best block known height into CConnman 
CConnman then passes the current best height into CNode at creation time.

This way CConnman/CNode have no dependency on main for height, and the signals
only move in one direction.

This also helps to prevent identity leakage a tiny bit. Before this change, an
attacker could theoretically make 2 connections on different interfaces. They
would connect fully on one, and only establish the initial connection on the
other. Once they receive a new block, they would relay it to your first
connection, and immediately commence the version handshake on the second. Since
the new block height is reflected immediately, they could attempt to learn
whether the two connections were correlated.

This is, of course, incredibly unlikely to work due to the small timings
involved and receipt from other senders. But it doesn't hurt to lock-in
nBestHeight at the time of connection, rather than letting the remote choose
the time.

bd72937dc4 net: move nLocalServices/nRelevantServices to CConnman 
These are in-turn passed to CNode at connection time. This allows us to offer
different services to different peers (or test the effects of doing so).

960cf2e405 net: move nLocalHostNonce to CConnman 
This behavior seems to have been quite racy and broken.

Move nLocalHostNonce into CNode, and check received nonces against all
non-fully-connected nodes. If there's a match, assume we've connected
to ourself.

eb3596f7c2 Do not add random inbound peers to addrman. 
We should learn about new peers via address messages.

An inbound peer connecting to us tells us nothing about
 its ability to accept incoming connections from us, so
 we shouldn't assume that we can connect to it based on
 this.

The vast majority of nodes on the network do not accept
 incoming connections, adding them will only slow down
 the process of making a successful connection in the
 future.

Nodes which have configured themselves to not announce would prefer we
 not violate their privacy by announcing them in GETADDR responses.

dbb1f640e6 Added feeler connections increasing good addrs in the tried table. 
Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes.
