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

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.
