This amends the session creation and auth status querying logic of the device UI
backend. On creation of new browser sessions we now store a PendingAuth flag
as part of the session that indicates a pending auth process that needs to be
awaited. On auth status queries, the server initiates a polling for the auth result
if it finds this flag to be true. Once the polling is completes, the flag is set to false.
Why this change was necessary: with regular browser settings, the device UI
frontend opens the control auth URL in a new tab and starts polling for the
results of the auth flow in the current tab. With certain browser settings (that
we still want to support), however, the auth URL opens in the same tab, thus
aborting the subsequent call to auth/session/wait that initiates the polling,
and preventing successful registration of the auth results in the session
status. The new logic ensures the polling happens on the next call to /api/auth
in these kinds of scenarios.
In addition to ensuring the auth wait happens, we now also revalidate the auth
state whenever an open tab regains focus, so that auth changes effected in one
tab propagate to other tabs without the need to refresh. This improves the
experience for all users of the web client when they've got multiple tabs open,
regardless of their browser settings.

This file was never truly necessary and has never actually been used in
the history of Tailscale's open source releases.
A Brief History of AUTHORS files
---
The AUTHORS file was a pattern developed at Google, originally for
Chromium, then adopted by Go and a bunch of other projects. The problem
was that Chromium originally had a copyright line only recognizing
Google as the copyright holder. Because Google (and most open source
projects) do not require copyright assignemnt for contributions, each
contributor maintains their copyright. Some large corporate contributors
then tried to add their own name to the copyright line in the LICENSE
file or in file headers. This quickly becomes unwieldy, and puts a
tremendous burden on anyone building on top of Chromium, since the
license requires that they keep all copyright lines intact.
The compromise was to create an AUTHORS file that would list all of the
copyright holders. The LICENSE file and source file headers would then
include that list by reference, listing the copyright holder as "The
Chromium Authors".
This also become cumbersome to simply keep the file up to date with a
high rate of new contributors. Plus it's not always obvious who the
copyright holder is. Sometimes it is the individual making the
contribution, but many times it may be their employer. There is no way
for the proejct maintainer to know.
Eventually, Google changed their policy to no longer recommend trying to
keep the AUTHORS file up to date proactively, and instead to only add to
it when requested: https://opensource.google/docs/releasing/authors.
They are also clear that:
> Adding contributors to the AUTHORS file is entirely within the
> project's discretion and has no implications for copyright ownership.
It was primarily added to appease a small number of large contributors
that insisted that they be recognized as copyright holders (which was
entirely their right to do). But it's not truly necessary, and not even
the most accurate way of identifying contributors and/or copyright
holders.
In practice, we've never added anyone to our AUTHORS file. It only lists
Tailscale, so it's not really serving any purpose. It also causes
confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header
in other open source repos which don't actually have an AUTHORS file, so
it's ambiguous what that means.
Instead, we just acknowledge that the contributors to Tailscale (whoever
they are) are copyright holders for their individual contributions. We
also have the benefit of using the DCO (developercertificate.org) which
provides some additional certification of their right to make the
contribution.
The source file changes were purely mechanical with:
git ls-files | xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g'

This is step 4 of making syspolicy a build-time feature.
This adds a policyclient.Get() accessor to return the correct
implementation to use: either the real one, or the no-op one. (A third
type, a static one for testing, also exists, so in general a
policyclient.Client should be plumbed around and not always fetched
via policyclient.Get whenever possible, especially if tests need to use
alternate syspolicy)

Starts using peer capabilities to restrict the management client
on a per-view basis. This change also includes a bulky cleanup
of the login-toggle.tsx file, which was getting pretty unwieldy
in its previous form.

Add logging of device management type for the web client auth flow. Namely,
this differentiates between viewing a node you do not own, viewing a local
tagged node, viewing a remote tagged node, managing a local node, and
managing a remote node.

client/web: skip check mode for non-tailscale.com control servers
Only enforce check mode if the control server URL ends in
".tailscale.com". This allows the web client to be used with headscale
(or other) control servers while we work with the project to add check
mode support (tracked in juanfont/headscale#1623).

This change removes the existing debug-web-client localapi endpoint
and replaces it with functions passed directly to the web.ServerOpts
when constructing a web.ManageServerMode client.
The debug-web-client endpoint previously handled making noise
requests to the control server via the /machine/webclient/ endpoints.
The noise requests must be made from tailscaled, which has the noise
connection open. But, now that the full client is served from
tailscaled, we no longer need to proxy this request over the localapi.
