This should fix an issue which would crop up if we ever needed to
pause the chain for a period of time - namely that nodes would not
sync again afterwards if they restarted during the pause.

75ead758 turned these into crashes in the event of a handshake failure, most
notably when a peer does not offer the expected services.
There are likely other cases that these assertions will find as well.

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.

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.

Prevent fingerprinting, disk-DoS with compact blocks

- Ignore GETBLOCKTXN requests for unknown blocks
Don't disconnect peers, or else we leak information that could be
used for fingerprinting.
- Ignore CMPCTBLOCK messages for pruned blocks
Also ignores CMPCTBLOCK announcements that have too little work. This is to
prevent disk-exhaustion DoS.
