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.

8272da638e api: unify security descriptors and disable for _DEBUG
When debugger is attached, CreateDirectory() with SYSTEM-only SID fails
with "This security ID may not be assigned as the owner of this object.
(Code 0x0000051B)".

ac6db7788a api: move documentation to .h and discontinue on static functions
While Doxygen correctly locates the function documentation when it is
written directly preceding the function body, Microsoft Visual Studio
IDE does not. The former requires the documentation to precede the
function declaration.

4c131caa7d api: honor locale when comparing case-insensitive
Quote from MSDN:
> You will need to call setlocale for _wcsicmp to work with Latin 1
> characters. The C locale is in effect by default, so, for example, ä
> will not compare equal to Ä.

d3a63116ba api: port GetInterface member from wireguard-go
Mind that this also fixes the order of adapter detection checks. A fast
test to eliminate non-Wintun adapters from iteration to speed things up
rendered the method incapable of detecting a non-Wintun adapter with the
name we are looking for.

ERROR_OBJECT_NOT_FOUND was replaced with ERROR_FILE_NOT_FOUND.
