9af27ba829 cmd/cloner: mangle "go:generate" in cloner.go
The "go generate" command blindly looks for "//go:generate" anywhere
in the file regardless of whether it is truly a comment.
Prevent this false positive in cloner.go by mangling the string

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

3618e8d8ac cmd/tailscaled: rename outbound HTTP proxy flag
The old name invited confusion:

* is this the HTTP proxy to use ourselves? (no, that's
  via an environment variable, per proxy conventions)
* is this for LetsEncrypt https-to-localhost-http
  proxying? (no, that'll come later)

So rename to super verbose --outbound-http-proxy-listen
before the 1.16.0 release to make it clear what it is.
It listens (serves) and it's for outbound, not inbound.

e016eaf410 cmd/tailscaled: conditionally flush Windows DNS cache on SessionChange
For the service, all we need to do is handle the `svc.SessionChange` command.
Upon receipt of a `windows.WTS_SESSION_UNLOCK` event, we fire off a goroutine to flush the DNS cache.
(Windows expects responses to service requests to be quick, so we don't want to do that synchronously.)

This is gated on an integral registry value named `FlushDNSOnSessionUnlock`,
whose value we obtain during service initialization.

(See [this link](https://docs.microsoft.com/en-us/windows/win32/api/winsvc/nc-winsvc-lphandler_function_ex) for information re: handling `SERVICE_CONTROL_SESSIONCHANGE`.)

ace2faf7ec cmd/tailscale: make debug profiling output - mean stdout
Because the macOS CLI runs in the sandbox, including the filesystem,
so users would be confused that -cpu-profile=prof.cpu succeeds but doesn't
write to their current directory, but rather in some random Library/Containers
directory somewhere on the machine (which varies depending on the Mac build
type: App Store vs System Extension)

efb84ca60d ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command
This was already possible on Linux if you ran tailscaled with --debug
(which runs net/http/pprof), but it requires the user have the Go
toolchain around.

Also, it wasn't possible on macOS, as there's no way to run the IPNExtension
with a debug server (it doesn't run tailscaled).

And on Windows it's super tedious: beyond what users want to do or
what we want to explain.

Instead, put it in "tailscale debug" so it works and works the same on
all platforms. Then we can ask users to run it when we're debugging something
and they can email us the output files.

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.
