Windows: Fix GCC printf format warnings due to DWORD/ULONG types

The Visual Studio compiler considers a long to always be 32-bits, so the
official Windows API headers define the DWORD and ULONG types as
unsigned long proper. GCC (and possibly other compilers) vary the width
of a long to match the build target, so this complicates printf format
strings for these two types because the underlying type is inconsistent.

Address this mess by introducing a macro that casts as necessary for the
compiler.

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD and Haiku userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).

libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
