3ec5be3f51 all: remove AUTHORS file and references to it
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'

safesocket, version: fix safesocket_darwin behavior for cmd/tailscale (#15275)
fixes tailscale/tailscale#15269

Fixes the various CLIs for all of the various flavors of tailscaled on
darwin.  The logic in version is updated so that we have methods that
return true only for the actual GUI app (which can beCLI) and the
order of the checks in localTCPPortAndTokenDarwin are corrected so
that the logic works with all 5 combinations of CLI and tailscaled.

safesocket: add isMacSysExt Check (#15192)
fixes tailscale/corp#26806

IsMacSysApp is not returning the correct answer... It looks like the
rest of the code base uses isMacSysExt (when what they really want
to know is isMacSysApp).   To fix the immediate issue (localAPI is broken
entirely in corp), we'll add this check to safesocket which lines up with
the other usages, despite the confusing naming.

safesocket: correct logic for determining if we're a macOS GUI client (#15187)
fixes tailscale/corp#26806

This was still slightly incorrect. We care only if the caller is the macSys
or macOs app.  isSandBoxedMacOS doesn't give us the correct answer
for macSys because technically, macsys isn't sandboxed.

safesocket: return an error for LocalTCPPortAndToken for tailscaled (#15144)
fixes tailscale/corp#26806

Fixes a regression where LocalTCPPortAndToken needs to error out early
if we're not running as sandboxed macos so that we attempt to connect
using the normal unix machinery.

safesocket: add ability for Darwin clients to set explicit credentials (#14702)
updates tailscale/corp#25687

The darwin appstore and standalone clients now support XPC and the keychain for passing user credentials securely between the gui process and an NEVPNExtension hosted tailscaled. Clients that can communicate directly with the network extension, via XPC or the keychain, are now expected to call SetCredentials and supply credentials explicitly, fixing issues with the cli breaking if the current user cannot read the contents of /Library/Tailscale due to group membership restrictions. This matches how those clients source and supply credentials to the localAPI http client.

Non-platform-specific code that has traditionally been in the client is moved to safesocket.

/Libraray/Tailscaled/sameuserproof has its permissions changed to that it's readably only by users in the admin group. This restricts standalone CLI access for and direct use of localAPI to admins.

version,cli,safesocket: detect non-sandboxed macOS GUI (#11369)
Updates ENG-2848

We can safely disable the App Sandbox for our macsys GUI, allowing us to use `tailscale ssh` and do a few other things that we've wanted to do for a while. This PR:

- allows Tailscale SSH to be used from the macsys GUI binary when called from a CLI
- tweaks the detection of client variants in prop.go, with new functions `IsMacSys()`, `IsMacSysApp()` and `IsMacAppSandboxEnabled()`

84ab040f02 safesocket: detect macsys from within tailscaled
Use the helper method from the version package to detect that we are
running the macsys network extension. This method does the same check
for the HOME environment variable (which works fine in most cases) as
well as the name of the executable (which is needed for the web client).

cmd/tailscale: Check App Store tailscaled dialable before selecting. (#9234)
PR #9217 attempted to fix the same issue, but suffered from not letting the
user connect to non-oss tailscaled if something was listening on the socket, as
the --socket flag doesn't let you select the mac apps.

Rather than leave the user unable to choose, we keep the mac/socket preference
order the same and check a bit harder whether the macsys version really is
running. Now, we prefer the App Store Tailscale (even if it's Stopped) and you
can use --socket to sswitch. But if you quit the App Store Tailscale, we'll try
the socket without needing the flag.

71029cea2d all: update copyright and license headers
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.
