Intermediate commit of work in progress on integrating the old code for OLE2-based generic drag and drop from Arhaeopteryx Software, from a long time ago in the GTK+ 1.3 timeframe. Does still not work and is as before not compiled in unless OLE2_DND is defined in gdkdnd-win32.c. (Thus, for inter-process DND, still only WM_DROPFILES style dropping of files on GTK+ apps works.) Related slight refactoring of other code that shouldn't change how it works. Add more global variables for run-time constants (once initialized) representing well-known GdkAtoms and registered Windows clipboard formats, as they with the generic DND code will be needed in several source files. Some improved debugging output.
