d9ee9a0d3f ipn: set BackendServer's notify earlier; don't require Start 
We've been slowly making Start less special and making IPN a
multi-connection "watch" bus of changes, but this Start specialness
had remained.

since that will fail as a dupe.

3b451509dd cmd/tailscale/cli: make advertise-{routes,exit-node} available unconditionally 
It was only Linux and BSDs before, but now with netstack mode, it also works on
Windows and darwin. It's not worth limiting it to certain platforms.

Tailscaled itself can complain/fail if it doesn't like the settings
for the mode/OS it's operating under.

2685260ba1 net/dns: add temporary fallback to quad-9 resolver for split-DNS testing. 
This allows split-DNS configurations to not break clients on OSes that
haven't yet been ported to understand split DNS, by falling back to quad-9
as a global resolver when handed an "impossible to implement"
split-DNS config.

Part of #953. Needs to be removed before shipping 1.8.
