[NTVDM]

Browse source 
- BIOS: Reorganize a bit the header, and close the input thread before closing the input handle (and not after).
- INT32: Fix a comment.
- CMOS: Put CMOS data into a structure called CMOS_MEMORY, introduce READ/WRITE_CMOS_DATA macros for simplifying code. Save CMOS memory into a file (à la Windows' NTVDM), which is loaded at startup.
