- Enable experimental sound support (only PC speaker for the moment, aka. uses beep.sys).
- Introduce a #define WORKING_TIMER which aim is to disable the currently problematic approximate performance counter value calculation done in order not to call QueryPerformanceCounter each time.
The problem is that we then compute a number of clock ticks for the PIT, which becomes negative, and therefore everything starts to hang.
Disabling this code and calling each time QueryPerformanceCounter, fixes everything; we gain in precision but we loose in performance...
A definitive fix must be found, [TheFlash] !!
This fixes sound (and hangs) in Advanced NetWars, Dangerous Dave, ElitePlus and Rescue Rover (the games that I've tested so far).

Part 2 of PIT + sound fix.
- Move port 61h management from speaker.c to the emulator.c module;
- Add PIT OUT callbacks support;
- Add (unimplemented) PitSetGate function (will be used later on).
Still WIP.

- 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).
svn path=/branches/ntvdm/; revision=61846
- 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).

- Shut up some DPRINTs in io.c and ntvdm.c
- I forgot to update the call to PitClock in the previous revision...

Welcome sound in Advanced NetWars!
However it won't work totally due to problems in the PIT or in the sound emulation (and as a result, the emulator will "hang").

Add two general-purpose variables to the interrupt handler stub stack.
Fix INT 29h so that it works correctly when the INT 10h, AH = 0Eh call is hooked.

- Move all the hardware initialization to EmulatorInitialize (since emulator.c can be viewed as support functions for emulating a PC motherboard) --> PS2 and VGA go there.
- Break bios.c into bios.c and kbdbios.c (the keyboard bios module) (according to the IBM documentation as well as other emulator sources or SeaBIOS or...).
- Move Exception handling from int32.c to emulator.c, because it's something tight to the emulator, not to the interrupt system by itself (yet it happens that INT 00h to 07h are commonly set to some exception handlers). In the bios.c, initialize those vectors with the default exception handler.
- Handling IRQs is done fully in bios.c now: introduce PicSetIRQMask and EnableHwIRQ helper functions (adapted from their equivalents from SeaBIOS) that allows the bios to set (and activate in the PIC) a given IRQ with its corresponding handler. Also introduce PicIRQComplete that serves as a PIC IRQ completer (i.e. sends the EOI to the right PIC(s)).
- Continuing on that, at the moment I set dumb default PIC IRQ handlers for IRQ 08h - 0Fh and IRQ 70h - 77h).
- By default I disable all the IRQs; there are then set on-demand with EnableHwIRQ.
- Rework the POST (aka. BiosInitialize function):
* the memory size is now get from the CMOS (as well as the extended memory size via INT 12h, AH=88h),
* then we initialize the interrupts,
* then platform hardware (ie. the chips) are initialized,
* and finally the keyboard and video bioses.
- As said before, move memory sizes into the CMOS.
- Simplify video bios initialization.

- Implement NtPrivilegedServiceAuditAlarm, the internal function SepAdtPrivilegedServiceAuditAlarm is not implemented yet.
- Stubplement SepAccessCheckAndAuditAlarm and make NtAccessCheckAndAuditAlarm, NtAccessCheckByTypeAndAuditAlarm, NtAccessCheckByTypeResultListAndAuditAlarm and NtAccessCheckByTypeResultListAndAuditAlarmByHandle (love that name) wrappers around it.
