- Add new type of debug print for windows loader
- Add address conversion routines for windows loader - Add stubs for PE loading, memory operations - Add some code to the LoadAndBootWindows() Some notes: - The windows loader is going to become some kind of a library in future, shared at least between freeldr and EFI loader. - The code in windows loader is specific to i386 architecture for now, but I add it to the "freeldr_base". I better separate it a bit later, after discussion with arty (because I hardly want compatibility with loading windows on PPC). svn path=/trunk/; revision=24350
