- Break the DOS source file into the "DOS BIOS" (also known in other places as ibmbio or io or...), which is in fact some kind of hardware abstraction layer, and the "DOS BDOS" kernel (also known in other places as ibmdos.com or msdos.sys or...).
- Add in DEM the possibility of loading the DOS from another files (WIP).

- Start to refactor the DOS sources:
Introduce the DEM (DOS Emulation) support library that is used by our built-in DOS, and that is used (via BOPs) by windows NT DOS (files: ntio.sys and ntdos.sys).
- Export some of DEM functions; stub most of them and implement the remaining ones (with existing code that we had in dos.c before).
