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.

testNodes have a reference to a testing.TB via their env.
Use it instead of making the caller pass theirs.
We did this in some methods but not others; finish the job.
This simplifies the call sites.

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.

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.

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.

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.

Allow users of CallbackRouter to supply a GetBaseConfig
implementation. This is expected to be used on Android,
which currently lacks both a) platform support for
Split-DNS and b) a way to retrieve the current DNS
servers.
iOS/macOS also use the CallbackRouter but have platform
support for SplitDNS, so don't need getBaseConfig.

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.
