Hermès Bélusca-Maïto 3c273ca1a9 [NTVDM]: Register functions are already declared via the inclusion of ddk/vddsvc.h. However still keep their definitions also in registers.h (yet #if 0'ed out) for reference.

Hermès Bélusca-Maïto e8d3c3e4bd [NTVDM]: Don't display an error message if the VDD registry key (or value) just doesn't exist: it significates we just don't have any VDD to load... 
Thanks to Lee Schroeder and oldman on the forum for having detected this :)

Shut up few DPRINT1s, and demote some DPRINT1s to DPRINTs but disable NDEBUG for now (enable it and you'll shut up the DPRINTs).

Load VDDs registered in HKLM\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers key, value "VDD" (of type REG_MULTI_SZ).
I still don't call FreeLibrary to unload them at the end of NTVDM's lifetime (otherwise we would have to store their handles in an array).

Hermès Bélusca-Maïto 610ee54a1a VDD really means "Virtual Device Drivers".

Studying the "vddtest" example mentioned in revision 61283 allowed me to see that valid VDD DLL "handles" start at 1 and cannot be equal to zero.
Add helper macros to convert from indices to handles. Fixes "vddtest" example.

Have fun at running it :)

- Thanks Thomas for having pointed me towards the fact that the NTVDM exports were really STDCALL and not CDECL (as I've thought first, because originally I was checking whether the getXX() functions were stdcall or not, and distinguishing VOID stdcall or cdecl functions without the symbols was hopeless).
- Halfplement and export Sim32pGetVDMPointer and MGetVdmPointer, needed to run correctly the RageStorm "galaxy" sample mentioned yesterday (see revision 61283). Now it loads and the dispatch call works \o/
- VDD_INIT_PROC and VDD_DISPATCH_PROC have the same signature --> rename them to VDD_PROC.

Have fun at testing!

Implement basic VDD support:
implement the (un)register & dispatch call BOP (called BOP_3RDPARTY): see "Undocumented DOS" by Schulman et al. page 267 (as always ;) ), as well as:
http://www.ragestorm.net/tutorial?id=27 - "Tutorial - Calling Win32 from DOS"
http://www.airborn.com.au/layout/vddtest.html - "DOS to 32 bit DLL under XP - an example" (almost the same explanations as the previous article)
http://sta.c64.org/blog/dosvddaccess.html - "Accessing Windows device drivers from DOS programs"
and...
... your lovely Win2k / Win2k3 DDK section: "Device Technologies/Other Devices/Devices Requiring VDDs" !!

Ready to test? :D
