c4110780bf lib/file: fix SetSparse on Windows 7 which fixes downloads of files > 250MB
Before this change we passed both lpOverlapped and lpBytesReturned as NULL.

> If lpOverlapped is NULL, lpBytesReturned cannot be NULL. Even when
> an operation produces no output data, and lpOutBuffer can be NULL,
> the DeviceIoControl function makes use of the variable pointed to by
> lpBytesReturned. After such an operation, the value of the variable
> is without meaning.

After this change we set lpBytesReturned to a valid pointer.

42d997f639 lib/file: reimplement os.OpenFile allowing rename/delete open files under Windows
Normally os.OpenFile under Windows does not allow renaming or deleting
open file handles.  This package provides equivelents for os.OpenFile,
os.Open and os.Create which do allow that.
