* adds new packet "netcheck" to do the checking of UDP, IPv6, and
nearest DERP server, and the Report type for all that (and more
in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
change/move) to print out the netcheck.Report.

Prefs has become a heavy object with non-memcpy copy
semantics. We should not pass such a thing by value.

We can't rely on a frontend to provide a control
server URL, so this naturally belongs in server-persisted
state.

On unix, we want to provide a full path to the desired unix socket.
On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.
For now, simplify the API down to exactly a path and a TCP port.

This is a prelude to supporting relaynode's --routes in
tailscaled. The daemon needs to remembers routes to
advertise, and the CLI needs to be able to change the
set of advertised routes. Prefs is the thing used for
both of these.

With this change, tailscaled can be restarted and reconnect
without interaction from `tailscale`, and `tailscale` is merely
there to provide login assistance and adjust preferences.

This test is skipped in tailscale/tailscale because it depends on
parts that haven't been released yet and was thus overlooked in the
git commit 79295b1138 cleanup.

It was previously used by the MacOS client, but it now does
something different. ipnserver should never obey a client's
request to exit.

The store is passed-in by callers of NewLocalBackend and
ipnserver.Run, but currently all callers are hardcoded to
an in-memory store. The store is unused.

This is a prelude to making it truly optional, once state
management has moved into the backend. For now though, it's
still required. This change is just isolating the bubbling-up
of the pointerification into other layers.

- It was only used in one currently-unused client.
- It's an imperative command, not a configuration setting.
- The LoginFlags stuff in controlclient feels like it needs
a refactor anyway.
I'll put this logic back once ipnd owns its state and Backend
commands reflect that.

The linter is strictly correct, but the code is structured
this way to avoid variable shadowing problems in the following
for loop. The context doesn't leak.
Staticcheck is correctly pointing out that this code is hard to
follow. However, this chunk of code is in service of enforcing
one frontend <> one backend, and we want to remove that limitation.
So, we'll just ignore the lint warning until this entire piece of
code goes away.
