Brad Fitzpatrick 5a9914a92f wgengine/netstack: don't remove 255.255.255.255/32 from netstack
The intent of the updateIPs code is to add & remove IP addresses
to netstack based on what we get from the netmap.

But netstack itself adds 255.255.255.255/32 apparently and we always
fight it (and it adds it back?). So stop fighting it.

Updates #2642 (maybe fixes? maybe.)

Brad Fitzpatrick 40e2b312b6 ipn/ipnserver, logpolicy: move Windows disk logging up earlier
This moves the Windows-only initialization of the filelogger into
logpolicy. Previously we only did it when babysitting the tailscaled
subprocess, but this meant that log messages from the service itself
never made it to disk. Examples that weren't logged to disk:

* logtail unable to dial out,
* DNS flush messages from the service
* svc.ChangeRequest messages (#3581)

This is basically the same fix as #3571 but staying in the Logf type,
and avoiding build-tagged file (which wasn't quite a goal, but
happened and seemed nice)

Fixes #3570

Brad Fitzpatrick 8f43ddf1a2 ipn/ipnlocal, health: populate self node's Online bit in tailscale status
One option was to just hide "offline" in the text output, but that
doesn't fix the JSON output.

The next option was to lie and say it's online in the JSON (which then
fixes the "offline" in the text output).

But instead, this sets the self node's "Online" to whether we're in an
active map poll.

Josh Bleecher Snyder 4691e012a9 tstest/integration: build binaries only once
The existing code relied on the Go build cache to avoid
needless work when obtaining the tailscale binaries.

For non-obvious reasons, the binaries were getting re-linked
every time, which added 600ms or so on my machine to every test.

Instead, build the binaries exactly once, on demand.
This reduces the time to run 'go test -count=5' from 34s to 10s
on my machine.

Brad Fitzpatrick adc97e9c4d cmd/tailscale: make --accept-routes default true on Windows, macOS GUI
One of the most annoying parts of using the Tailscale CLI on Windows
and the macOS GUI is that Tailscale's GUIs default to running with
"Route All" (accept all non-exitnode subnet routes) but the CLI--being
originally for Linux--uses the Linux default, which is to not accept
subnets.

Which means if a Windows user does, e.g.:

    tailscale up --advertise-exit-node
Or:
    tailscale up --shields-up

... then it'd warn about reverting the --accept-routes option, which the user
never explicitly used.

Instead, make the CLI's default match the platform/GUI's default.

Josh Bleecher Snyder 63cd581c3f safesocket: add ConnectionStrategy, provide control over fallbacks
fee2d9fad added support for cmd/tailscale to connect to IPNExtension.
It came in two parts: If no socket was provided, dial IPNExtension first,
and also, if dialing the socket failed, fall back to IPNExtension.

The second half of that support caused the integration tests to fail
when run on a machine that was also running IPNExtension.
The integration tests want to wait until the tailscaled instances
that they spun up are listening. They do that by dialing the new
instance. But when that dial failed, it was falling back to IPNExtension,
so it appeared (incorrectly) that tailscaled was running.
Hilarity predictably ensued.

If a user (or a test) explicitly provides a socket to dial,
it is a reasonable assumption that they have a specific tailscaled
in mind and don't want to fall back to IPNExtension.
It is certainly true of the integration tests.

Instead of adding a bool to Connect, split out the notion of a
connection strategy. For now, the implementation remains the same,
but with the details hidden a bit. Later, we can improve that.

Brad Fitzpatrick 39ffa16853 net/dnscache, net/tsdial: add DNS caching to tsdial UserDial
This is enough to handle the DNS queries as generated by Go's
net package (which our HTTP/SOCKS client uses), and the responses
generated by the ExitDNS DoH server.

This isn't yet suitable for putting on 100.100.100.100 where a number
of different DNS clients would hit it, as this doesn't yet do
EDNS0. It might work, but it's untested and likely incomplete.

Likewise, this doesn't handle anything about truncation, as the
exchanges are entirely in memory between Go or DoH. That would also
need to be handled later, if/when it's hooked up to 100.100.100.100.

The caller of func run said:

    // No need to log; the func already did

But that wasn't true. Some return paths didn't log.

So instead, return rich errors and have func main do the logging,
so we can't miss anything in the future.

Prior to this, safesocket.Listen for instance was causing tailscaled
to os.Exit(1) on failure without any clue as to why.
