Brad Fitzpatrick 39b9ab3522 cmd/tailscaled: rename isUserspace to useNetstack
The bool was already called useNetstack at the caller.
isUserspace (to mean netstack) is confusing next to wgengine.NewUserspaceEngine, as that's
a different type of 'userspace'.

Josh Bleecher Snyder 34d4943357 all: gofmt -s
The code is not obviously better or worse, but this makes the little warning
triangle in my editor go away, and the distraction removal is worth it.

Denton Gentry 35ab4020c7 wgengine/monitor: Linux fall back to polling
Google Cloud Run does not implement NETLINK_ROUTE RTMGRP.
If initialization of the netlink socket or group membership
fails, fall back to a polling implementation.

David Anderson 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.

David Anderson dbe4f6f42d net/dns/resolver: unexport Resolve and ResolveReverse.
They're only used internally and in tests, and have surprising

Brad 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 1f583a895e ipn/ipnlocal: stop sending machine key to frontends
We were going to remove this in Tailscale 1.3 but forgot.

This means Tailscale 1.8 users won't be able to downgrade to Tailscale
1.0, but that's fine.

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
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.

Fixes #1626

Denton Gentry 54ba6194f7 interfaces: allow IPv6 ULA as a valid address.
IPv6 Unique Local Addresses are sometimes used with Network
Prefix Translation to reach the Internet. In that respect
their use is similar to the private IPv4 address ranges
10/8, 172.16/12, and 192.168/16.

Treat them as sufficient for AnyInterfaceUp(), but specifically
exclude Tailscale's own IPv6 ULA prefix to avoid mistakenly
trying to bootstrap Tailscale using Tailscale.

This helps in supporting Google Cloud Run, where the addresses
are 169.254.8.1/32 and fddf:3978:feb1:d745::c001/128 on eth1.

Since this is unexpected anyway, panic instead.
