Brad Fitzpatrick c56e94af2d ipn: avoid useless no-op WriteState calls
Rather than make each ipn.StateStore implementation guard against
useless writes (a write of the same value that's already in the
store), do writes via a new wrapper that has a fast path for the
unchanged case.

This then fixes profileManager's flood of useless writes to AWS SSM,
etc.

Maisem Ali e0d291ab8a ipn/store: add support for stores to hook into a custom dialer
For stores like k8s secrets we need to dial out to the k8s API as though Tailscale
wasn't running. The issue currently only manifests when you try to use an exit node
while running inside a k8s cluster and are trying to use Kubernetes secrets as the
backing store.

This doesn't address cmd/containerboot, which I'll do in a follow up.

Will Norris 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.

Tom DNetto 4001d0bf25 assorted: plumb tka initialization & network-lock key into tailscaled
- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
 - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

Maxime VISONNEAU 4528f448d6 ipn/store/aws, cmd/tailscaled: add AWS SSM ipn.StateStore implementation
From https://github.com/tailscale/tailscale/pull/1919 with
edits by bradfitz@.

This change introduces a new storage provider for the state file. It
allows users to leverage AWS SSM parameter store natively within
tailscaled, like:

    $ tailscaled --state=arn:aws:ssm:eu-west-1:123456789:parameter/foo

Known limitations:
- it is not currently possible to specific a custom KMS key ID

RELNOTE=tailscaled on Linux supports using AWS SSM for state

Brad Fitzpatrick 3b3994f0db ipn{,/localapi,ipnlocal}: infer cert dir from state file location
This fixes "tailscale cert" on Synology where the var directory is
typically like /volume2/@appdata/Tailscale, or any other tailscaled
user who specifies a non-standard state file location.

This is a interim fix on the way to #2932.

Aaron Klotz 21e9f98fc1 ipn, paths: unconditionally attempt to set state dir perms, but only if the state dir is ours
We unconditionally set appropriate perms on the statefile dir.

We look at the basename of the statefile dir, and if it is "tailscale", then
we set perms as appropriate.

Aaron Klotz 9ebb5d4205 ipn, paths: ensure that the state directory for Windows has the correct perms
ProgramData has a permissive ACL. For us to safely store machine-wide
state information, we must set a more restrictive ACL on our state directory.
We set the ACL so that only talescaled's user (ie, LocalSystem) and the
Administrators group may access our directory.

We must include Administrators to ensure that logs continue to be easily
accessible; omitting that group would force users to use special tools to
log in interactively as LocalSystem, which is not ideal.

(Note that the ACL we apply matches the ACL that was used for LocalSystem's
AppData\Local).

There are two cases where we need to reset perms: One is during migration
from the old location to the new. The second case is for clean installations
where we are creating the file store for the first time.

Josh Bleecher Snyder 56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.

Brad Fitzpatrick 515866d7c6 ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows
This partially (but not yet fully) migrates Windows to tailscaled's
StateStore storage system.

This adds a new bool Pref, ForceDaemon, defined as:

// ForceDaemon specifies whether a platform that normally
// operates in "client mode" (that is, requires an active user
// logged in with the GUI app running) should keep running after the
// GUI ends and/or the user logs out.
//
// The only current applicable platform is Windows. This
// forced Windows to go into "server mode" where Tailscale is
// running even with no users logged in. This might also be
// used for macOS in the future. This setting has no effect
// for Linux/etc, which always operate in daemon mode.

Then, when ForceDaemon becomes true, we now write use the StateStore
to track which user started it in server mode, and store their prefs
under that key.

The ipnserver validates the connections/identities and informs that
LocalBackend which userid is currently in charge.

The GUI can then enable/disable server mode at runtime, without using
the CLI.

But the "tailscale up" CLI was also fixed, so Windows users can use
authkeys or ACL tags, etc.
