* 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.
