da4cc8bbb4 net/dns: handle all possible translations of high-level DNS config. 
With this change, all OSes can sort-of do split DNS, except that the
default upstream is hardcoded to 8.8.8.8 pending further plumbing.
Additionally, Windows 8-10 can do split DNS fully correctly, without
the 8.8.8.8 hack.

Part of #953.

90f82b6946 net/dns/resolver: add live reconfig, plumb through to ipnlocal. 
The resolver still only supports a single upstream config, and
ipn/wgengine still have to split up the DNS config, but this moves
closer to unifying the DNS configs.

As a handy side-effect of the refactor, IPv6 MagicDNS records exist
now.

53cfff109b ipn: replace SetWantRunning(bool) with EditPrefs(MaskedPrefs) 
This adds a new ipn.MaskedPrefs embedding a ipn.Prefs, along with a
bunch of "has bits", kept in sync with tests & reflect.

Then it adds a Prefs.ApplyEdits(MaskedPrefs) method.

Then the ipn.Backend interface loses its weirdo SetWantRunning(bool)
method (that I added in 483141094c for "tailscale down")
and replaces it with EditPrefs (alongside the existing SetPrefs for now).

Then updates 'tailscale down' to use EditPrefs instead of SetWantRunning.

In the future, we can use this to do more interesting things with the
CLI, reconfiguring only certain properties without the reset-the-world
"tailscale up".

1bd14a072c cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API 
Instead of having the CLI check whether IP forwarding is enabled, ask
tailscaled. It has a better idea. If it's netstack, for instance, the
sysctl values don't matter. And it's possible that only the daemon has
permission to know.
