- Add new type of debug print for windows loader

- 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).
