This makes our intentions a lot more clear, and in case we ever add
other version functions, makes the forward path simpler.

This requires us to make some insane conversions between INF date,
JavaScript time, and finally Windows file time. The point is to mimic
SystemTimeToFileTime, which is what SpInf.dll's pSetupStringToDriverDate
does on the YYYY-MM-DD from the INF.
The result is that we no longer have to parse an ancient text format in
C at runtime.

The iphlpapi takes both LUIDs and GUIDs but prefers LUIDs, so exposing
the NET_LUID makes sense. However, we were previously exposing the
configuration GUID, rather than the net GUID, which is confusing, so
just make it all go away.

It would be better to do this only if either nci.def or nci.h are newer
than nci.lib, but who knows if msbuild is expressive enough for this.

It'd be nicer to do this via
if (is_defined(HAVE_WHATEVER))
But MSVC won't work with the linux kernel macros for this. Ongoing
research.
Nevertheless, this makes most of the program always pass through the
compiler's type checker, only to have dead code removed later.

I don't like this solution, but I don't see much other choice. It's not
in uuid.lib or anywhere like that.

This is an appalling hack. We need the lib tool to generate a coff lib
with the "undecorate" parameter. And apparently the only way to do this
with the MSVC tools is by making a stub object, and then rewriting the
symbols using the def file. See Q131313 for Microsoft-sanctioned
details.

When Windows 7-8.1 support is sunset, there will be no more EV driver
deployment at all.

When we install the Wintun driver to the store, we get exact oem<nn>.inf
filename of the driver in the store we just installed. Since the
installation should be only temporarily, we should uninstall only the
driver we installed.
This also eliminates the need for iterating driver store speeding up
things.
The code we removed was inherited from the installer.dll, where it made
perfect sense to remove all installed Wintun drivers in the update
process.

With all the platforms (including ARM) having at least one driver now,

This adds the ARM driver to the list of Wintun drivers we compile for
future deployment. Since we're not in position to test it in the real
world, any feedback is greatly appreciated.

Silently ignoring truncation of the strings(like adapter and pool names,
registry paths etc.) leads to strange failures later down the road (like
registry key not found) masking the true reason of the failure. This
makes troubleshooting difficult.

We must not use the process heap, as it is changeable. Client may change
it causing our HeapFree() to use wrong heap.

Rather than every client reinvent the art of using the Wintun and its

RegistryQueryString() may produce one or more "File not found" errors
when called from RegistryQueryStringWait() - which is expected while
waiting. Those errors were annoying and awkward to read in the log.
Furthermore, should RegistryQueryString() fail, it already displays
detailed Windows error message and the parent's logging was simplified
to prevent repetitions in the log.

The WintunCreateAdapter()+CreateAdapter() and WintunDeleteAdapter()+
DeleteAdapter() communicate using Unicode anonymous pipes now. This
allows the WintunCreateAdapter() to exactly determine the adapter
CreateAdapter() just created by its GUID rather than its name - avoiding
the possible ambiguity caused by same-adapter-name ordinal suffixes.
This also allows exact retrieval of the result code and pending reboot
flag from the rundll32 child process.
Furthermore, CreateAdapter() and DeleteAdapter() are now available in
_DEBUG for all platforms to allow testing. It took a #pragma comment(
linker, "/EXPORT") trick to stop compiler from decorating function names
and exporting as _CreateAdapter@16() and _DeleteAdapter@16() in x86.

The SDK header for deployment containing datatype and function

As we shall not distribute MSVC wintun.lib files, making clients need to
use GetProcAddress(), this file contains function type declarations
rather then __declspec(dllimport) function declarations.
