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`.)

Fixes #2956

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

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.

Windows has a public dns.Flush used in router_windows.go.
However that won't work for platforms like Linux, where

280c84e46a ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData%
C:\WINDOWS\system32\config\systemprofile\AppData\Local\
is frequently cleared for almost any reason: Windows updates,
System Restore, even various System Cleaner utilities.

The server-state.conf file in AppData\Local could be deleted
at any time, which would break login until the node is removed
from the Admin Panel allowing it to create a new key.

Carefully copy any AppData state to ProgramData at startup.
If copying the state fails, continue to use AppData so at
least there will be connectivity. If there is no state,
use ProgramData.

We also migrate the log.conf file. Very old versions of
Tailscale named the EXE tailscale-ipn, so the log conf was
tailscale-ipn.log.conf and more recent versions preserved
this filename and cmdName in logs. In this migration we
always update the filename to
c:\ProgramData\Tailscale\tailscaled.log.conf
