faf7d3771c api: connect rundll32 child with parent using stdout and stderr
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.

449876fdfd api: introduce wintun.h
The SDK header for deployment containing datatype and function
declarations for use by C/C++ clients.

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.
