We cannot directly pass a flat domain name into NetUserGetInfo; we must
resolve the address of a domain controller first.
This PR implements the appropriate resolution mechanisms to do that, and
also exposes a couple of new utility APIs for future needs.

S4U logons do not automatically load the associated user profile. In this
PR we add UserProfile to handle that part. Windows docs indicate that
we should try to resolve a remote profile path when present, so we attempt
to do so when the local computer is joined to a domain.

This PR is all about adding functionality that will enable the installer's
upgrade sequence to terminate processes belonging to the previous version,
and then subsequently restart instances belonging to the new version within
the session(s) corresponding to the processes that were killed.
There are multiple parts to this:
* We add support for the Restart Manager APIs, which allow us to query the
OS for a list of processes locking specific files;
* We add the RestartableProcess and RestartableProcesses types that query
additional information about the running processes that will allow us
to correctly restart them in the future. These types also provide the
ability to terminate the processes.
* We add the StartProcessInSession family of APIs that permit us to create
new processes within specific sessions. This is needed in order to
properly attach a new GUI process to the same RDP session and desktop that
its previously-terminated counterpart would have been running in.
* I tweaked the winutil token APIs again.
* A lot of this stuff is pretty hard to test without a very elaborate
harness, but I added a unit test for the most complicated part (though it
requires LocalSystem to run).

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.

* We update wingoes to pick up new version information functionality
(See pe/version.go in the https://github.com/dblohm7/wingoes repo);
* We move the existing LogSupportInfo code (including necessary syscall
stubs) out of util/winutil into a new package, util/osdiag, and implement
the public LogSupportInfo function may be implemented for other platforms
as needed;
* We add a new reason argument to LogSupportInfo and wire that into
localapi's bugreport implementation;
* We add module information to the Windows implementation of LogSupportInfo
when reason indicates a bugreport. We enumerate all loaded modules in our
process, and for each one we gather debug, authenticode signature, and
version information.

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.

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.
Updates #6865

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.
