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 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.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

This doesn't change any behaviour for now, other than maybe running a
full netcheck more often. The intent is to start gathering data on
captive portals, and additionally, seeing this in the 'tailscale
netcheck' command should provide a bit of additional information to
users.

This lets the control plane can make HTTP requests to nodes.
Then we can use this for future things rather than slapping more stuff

Use it instead of making the caller pass theirs.
We did this in some methods but not others; finish the job.

magicsock was hanging onto its netmap on logout,

After logout, there should be no peers.

If you're using -verbose-tailscaled, you're doing in-the-weeds debugging,

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.

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.

Filch doesn't like having multiple processes competing
for the same log files (#937).
Parallel integration tests were all using the same log files.
Add a TS_LOGS_DIR env var that the integration test can use
to use separate log files per test.

The maximum unix domain socket path length on darwin is 104 bytes,
including the trailing NUL.
On my machine, the path created by some newly added tests (6eecf3c9)
was too long, resulting in cryptic test failures.
Shorten the names of the tests, and add a check to make
the diagnosis easier next time.

Regression from 6d10655dc3, which added
UpdatePrefs but didn't write it out to disk.
I'd planned on adding tests to state_test.go which is why I'd earlier
added 46896a9311 to prepare for making
such persistence tests easier to write, but turns out state_test.go
didn't even test UpdatePrefs, so I'm staying out of there.
Instead, this is tested using integration tests.

This adapts the existing in-process logcatcher from tstest/integration
into a public type and uses it on the side of testcontrol. This also
fixes a bug in the Alpine Linux OpenRC unit that makes every value in
`/etc/default/tailscaled` exported into tailscaled's environment, a-la
systemd [Service].EnviromentFile.

Previously this test would reach out to the public DERP servers in order
to help machines connect with eachother. This is not ideal given our
plans to run these tests completely disconnected from the internet. This
patch introduces an in-process DERP server running on its own randomly
assigned HTTP port.
