Chun-wei Fan 6e169c1490 python: Port python 3.x module to Windows 
On Windows, we don't have fcntl() which helps us to find out how a file was
opened, so we need to resort to the Windows API NtQueryInformationFile() in
ntdll.dll to help us, and compare the file access modes as appropriate to
deduce the modes we want to pass into fdopen().

As all official Python 3.x releases are built against newer Windows CRTs that
toughen checks on the validity of the file descriptor when we convert the fd to
a native Windows File Handle using _get_osfhandle(), we need to define an empty
handler so that the program does not abort if the fd that was passed in was
invalid; instead, we just return NULL if _get_osfhandle() could not return us a
valid Windows File Handle.
