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.

abf6962144 api: simplify driver removal
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.
