9f3d466791 api: remove WintunOpenAdapterDeviceObject
Discourage use of kernel interface, which gives us more flexibility if
we ever want to change it.

677ba8680f wintun: extract inf driverver at compile time into C header
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.

8963f7258e api: remove guid getter
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.

1201c9f346 api: ensure more code compiles by using dead code elimination
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.
