Brad FitzpatrickandBrad Fitzpatrick 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".

Brad Fitzpatrick 1bd14a072c cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API 
Instead of having the CLI check whether IP forwarding is enabled, ask

sysctl values don't matter. And it's possible that only the daemon has
permission to know.

Brad Fitzpatrick 7f174e84e6 net/interfaces: remove mutating methods, add EqualFiltered instead 
Now callers (wgengine/monitor) don't need to mutate the state to remove
boring interfaces before calling State.Equal. Instead, the methods
to remove boring interfaces from the State are removed, as is
the reflect-using Equal method itself, and in their place is
a new EqualFiltered method that takes a func predicate to match
interfaces to compare.

And then the FilterInteresting predicate is added for use
with EqualFiltered to do the job that that wgengine/monitor
previously wanted.

Now wgengine/monitor can keep the full interface state around,
including the "boring" interfaces, which we'll need for peerapi on
macOS/iOS to bind to the interface index of the utunN device.

Brad Fitzpatrick 0994a9f7c4 wgengine{,/magicsock}: fix, improve "tailscale ping" to default routes and subnets 
e.g.

$ tailscale ping 1.1.1.1
exit node found but not enabled

$ tailscale ping 10.2.200.2
node "tsbfvlan2" found, but not using its 10.2.200.0/24 route

$ sudo tailscale  up --accept-routes
$ tailscale ping 10.2.200.2
pong from tsbfvlan2 (100.124.196.94) via 10.2.200.34:41641 in 1ms

$ tailscale ping mon.ts.tailscale.com
pong from monitoring (100.88.178.64) via DERP(sfo) in 83ms
pong from monitoring (100.88.178.64) via DERP(sfo) in 21ms
pong from monitoring (100.88.178.64) via [2604:a880:4:d1::37:d001]:41641 in 22ms

This necessarily moves code up from magicsock to wgengine, so we can
look at the actual wireguard config.

Brad Fitzpatrick 0406a7436a cmd/tailscale/cli: use double hypens, make default usage func more clear 
Mash up some code from ffcli and std's flag package to make a default
usage func that's super explicit for those not familiar with the Go
style flags. Only show double hyphens in usage text (but still accept both),
and show default values, and only show the proper usage of boolean flags.
