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.

b3ceca1dd7 wgengine/...: split into multiple receive functions
Upstream wireguard-go has changed its receive model.
NewDevice now accepts a conn.Bind interface.

The conn.Bind is stateless; magicsock.Conns are stateful.
To work around this, we add a connBind type that supports
cheap teardown and bring-up, backed by a Conn.

The new conn.Bind allows us to specify a set of receive functions,
rather than having to shoehorn everything into ReceiveIPv4 and ReceiveIPv6.
This lets us plumbing DERP messages directly into wireguard-go,
instead of having to mux them via ReceiveIPv4.

One consequence of the new conn.Bind layer is that
closing the wireguard-go device is now indistinguishable
from the routine bring-up and tear-down normally experienced
by a conn.Bind. We thus have to explicitly close the magicsock.Conn
when the close the wireguard-go device.

One downside of this change is that we are reliant on wireguard-go
to call receiveDERP to process DERP messages. This is fine for now,
but is perhaps something we should fix in the future.

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".

control/controlclient: sign RegisterRequest (#1549)
control/controlclient: sign RegisterRequest

Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.

There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.

gVisor fixed their google/gvisor#1446 so we can include gVisor mode

A few minor upstream API changes, as normal.

cc99059fc2 Revert "--advertise-routes option enabled in Mac tailscale CLI; it checks for IP forwarding enabled"
This reverts commit 08949d4ef1.

I think this code was aspirational. There's no code that sets up the
appropriate NAT code using pfctl/etc. See #911 and #1475.

c136f48b79 cmd/tailscale/cli: restore hidden debug subcommand
The debub subcommand was moved in
6254efb9ef because the monitor brought
in tons of dependencies to the cmd/tailscale binary, but there wasn't
any need to remove the whole subcommand itself.

Add it back, with a tool to dump the local daemon's goroutines.

c0cdca6d06 cmd/tailscaled, logtail: share link monitor from wgengine to logtail
Part of overall effort to clean up, unify, use link monitoring more,
and make Tailscale quieter when all networks are down. This is especially
bad on macOS where we can get killed for not being polite it seems.
(But we should be polite in any case)
