* OriginalAddr -> SocketAddr OriginalAddr records the originally dialed address for outbound peers, rather than the peer's self reported address. For inbound peers, it was nil. Here, we rename it to SocketAddr and for inbound peers, set it to the RemoteAddr of the connection. * use SocketAddr Numerous places in the code call peer.NodeInfo().NetAddress(). However, this call to NetAddress() may perform a DNS lookup if the reported NodeInfo.ListenAddr includes a name. Failure of this lookup returns a nil address, which can lead to panics in the code. Instead, call peer.SocketAddr() to return the static address of the connection. * remove nodeInfo.NetAddress() Expose `transport.NetAddress()`, a static result determined when the transport is created. Removing NetAddress() from the nodeInfo prevents accidental DNS lookups. * fixes from review * linter * fixes from review
