f7c2ea4ded api: retry on ERROR_TRANSACTION_NOT_ACTIVE when disabling dead GW detect 
There seems to be a race in the TCP/IP adapter registry key. Sometimes,
the adapter TCP/IP key is created, but setting the value
EnableDeadGWDetect fails with ERROR_TRANSACTION_NOT_ACTIVE.

0d214d7254 api: do not call UpdateDriverForPlugAndPlayDevicesW 
This seems to reset a number of device properties, and our update flow
seems to update old adapters without needing to call this.

8ec14e5f6d api: take pool mutex when deleting 
This prevents us from racing with driver deletion. Mutexes are
recursive, so we shouldn't deadlock if called from Enum.

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.
