Rewrite the VGA emulation.
Nah, it's a joke!
- Store VGA registers setup in VGA_REGISTERS structure.
- Improve BiosSetVideoMode and introduce a VgaSetRegisters function for setting VGA regs.
- Initialize Bda->CrtBasePort: it is used to determine the address of some I/O ports which depend on whether we are in color or monochrome mode.
- Add UnregisterIoPort in io.c (and fix some DPRINTs) (needed for VGA).
- When setting the misc. VGA register, check whether we're going to monochrome emulation, and reset some port addresses in that case.

- Remove some DPRINTs.
- Fix a bug in VgaEnterGraphicsMode (erroneous change of the real saved resolution when going into DoubleVision(TM) mode).
- Do not update the text cursor when being in graphics mode (otherwise I've already hit some ScanlineSize==0 problems) <-- [TheFlash], can you recheck that, please?
- Little optimisation: do not do anything in VgaRefreshDisplay if nothing has to be done.

- Move some PS/2 initialization from bios.c to ps2.c
- NULLify interrupt entries which are in fact pointers to data tables.
- Add a framework for adding I/O port handlers.

Implement the use of palettes for text mode. Adapted from a patch by Hermes Belusca-Maito.
Reset the palette during every BIOS video mode switch.

Synchronize with trunk again for SetConsolePalette.
Implement VGA palettes for graphics mode and DAC register access.
svn path=/branches/ntvdm/; revision=59713
- Fix usage of the console framebuffer mutex (used only with graphics screen buffers).
- Do not check for text/graphics mode when updating each scan line, in VgaUpdateFramebuffer.
svn path=/branches/ntvdm/; revision=59673
- Check return value of VgaEnterGraphicsMode (because CreateConsoleScreenBuffer can fail), and create VgaEnterTextMode and VgaLeaveTextMode helpers.
- Don't declare variables inside loops.
svn path=/branches/ntvdm/; revision=59668
- Don't leak console input/output handles when opening them in BiosInitialize.
- Deinitialize the emulator in the reverse order it was initialized.
- Simplify VgaGetVideoBaseAddress and VgaGetVideoLimitAddress and use the former one in VgaTranslate[Read-Write]Address.
- Use only unicode Win32 APIs where it's needed.
