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.

cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.

cmd/tailscaled, util/winutil: log our registry keys during tailscaled startup In order to improve our ability to understand the state of policies and registry settings when troubleshooting, we enumerate all values in all subkeys. x/sys/windows does not already offer this, so we need to call RegEnumValue directly. For now we're just logging this during startup, however in a future PR I plan to also trigger this code during a bugreport. I also want to log more than just registry.

util/winutil: add RegisterForRestart, allowing programs to indicate their preferences to the Windows restart manager In order for the installer to restart the GUI correctly post-upgrade, we need the GUI to be able to register its restart preferences. This PR adds API support for doing so. I'm adding it to OSS so that it is available should we need to do any such registrations on OSS binaries in the future.
