Log:
[DDK:NT_VDD]
Declare some VDM memory services.
[NTVDM]
- Almost all of the XXXInitialize functions just return TRUE always, so VOIDify them
instead (since they always succeed).
- Move almost all of the hardware initialization inside EmulatorInitialize.
- Move pure console initialization/mode-saving/cleanup code into ConsoleInit/Cleanup
functions in ntvdm.c instead of in bios.c.
