wgengine/tsdns: replace connections when net link changes (macOS) When the network link changes, existing UDP sockets fail immediately and permanently on macOS. The forwarder set up a single UDP conn and never changed it. As a result, any time there was a network link change, all forwarded DNS queries failed. To fix this, create a new connection when send requests fail because of network unreachability. This change is darwin-only, although extended it to other platforms should be straightforward.

ipn, wgengine, magicsock, tsdns: be quieter and less aggressive when offline If no interfaces are up, calm down and stop spamming so much. It was noticed as especially bad on Windows, but probably was bad everywhere. I just have the best network conditions testing on a Windows VM. Updates #604
