network-security: Prevent infinite sync challenges

An attack I spotted through the logs of a node: peer connects, peer
sends a sync challenge which requires 20 blocks to be read from disk and
sent over the network, and then disconnects. Continues this forever.

To mitigate this attack, each sync challenge is now punished at 50
points reputation. So after 20 such sync challenges from the same IP
address, this IP address will be banned.
