9972c02b60 cmd/tailscale/cli: don't let up change prefs based on implicit flag values 
This changes the behavior of "tailscale up".

Previously "tailscale up" always did a new Start and reset all the settings.

Now "tailscale up" with no flags just brings the world [back] up.
(The opposite of "tailscale down").

But with flags, "tailscale up" now only is allowed to change
preferences if they're explicitly named in the flags. Otherwise it's
an error. Or you need to use --reset to explicitly nuke everything.

RELNOTE=tailscale up change

4c3f7c06fc ipn/ipnlocal: be consistent in not logging when no notify registered 
Some paths already didn't. And in the future I hope to shut all the
notify funcs down end-to-end when nothing is connected (as in the
common case in tailscaled).  Then we can save some JSON encoding work.

d9ee9a0d3f ipn: set BackendServer's notify earlier; don't require Start

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.
