It would just fail the entire pkg, but would not print any
logs. It was already tracking all the logs, so have it emit
them when the pkg fails/times out.

If Start was called multiple times concurrently, it would
create a new client and shutdown the previous one. However
there was a race possible between shutting down the old one
and assigning a new one where the concurent goroutine may
have assigned another one already and it would leak.

resetControlClientLocked is called while b.mu was held and
would call cc.Shutdown which would wait for the observer queue
to drain.
However, there may be active callbacks from cc already waiting for
b.mu resulting in a deadlock.
This makes it so that resetControlClientLocked does not call
Shutdown, and instead just returns the value.
It also makes it so that any status received from previous cc
are ignored.

We already had a path on the web client server struct, but hadn't
plumbed it through to the CLI. Add that now and use it for Synology and
QNAP instead of hard-coding the path. (Adding flag for QNAP is
tailscale/tailscale-qpkg#112) This will allow supporting other
environments (like unraid) without additional changes to the client/web
package.
Also fix a small bug in unraid handling to only include the csrf token
on POST requests.

I noticed that failed tests were leaving aroudn stray tailscaled processes
on macOS at least.
To repro, add this to tstest/integration:
func TestFailInFewSeconds(t *testing.T) {
t.Parallel()
time.Sleep(3 * time.Second)
os.Exit(1)
t.Fatal("boom")
}
Those three seconds let the other parallel tests (with all their
tailscaled child processes) start up and start running their tests,
but then we violently os.Exit(1) the test driver and all the children
were kept alive (and were spinning away, using all available CPU in
gvisor scheduler code, which is a separate scary issue)

We want the overall state (used only for tests) to be computed from
the individual states of each component, rather than moving the state
around by hand in dozens of places.
In working towards that, we found a lot of things to clean up.

During Shutdown of an ephemeral node, we called Logout (to best effort
delete the node earlier), which then called back into
resetForProfileChangeLockedOnEntry, which then tried to Start
again. That's all a waste of work during shutdown and complicates
other cleanups coming later.

We already removed the async API, make it more sync and remove
the FinishLogout state too.
This also makes the callback be synchronous again as the previous
attempt was trying to work around the logout callback resulting
in a client shutdown getting blocked forever.

We have cases where the SetControlClientStatus would result in
a Shutdown call back into the auto client that would block
forever. The right thing to do here is to fix the LocalBackend
state machine but thats a different dumpster fire that we
are slowly making progress towards.
This makes it so that the SetControlClientStatus happens in a
different goroutine so that calls back into the auto client
do not block.
Also add a few missing mu.Unlocks in LocalBackend.Start.

As a fallback to package managers, allow updating tailscale that was

Instead of trying to use the user config dir, and then fail back to the
OS temp dir, just always use the temp dir. Also use a filename that is
less likely to cause collisions.
This addresses an issue on a test synology instance that was
mysteriously failing because there was a file at /tmp/tailscale. We
could still technically run into this issue if a
/tmp/tailscale-web-csrf.key file exists, but that seems far less likely.

While investigating the fix in 7538f38671,
I was curious why the testwrapper didn't fail. Turns out if the test
times out and there was no explicit failure, the only message we get
is that the overall pkg failed and no failure information about the
individual test. This resulted in a 0 exit code.
This fixes that by failing the explicit case of the pkg failing when
there is nothing to retry for that pkg.
