1f2d9ca668 Added DDC stub for the Cirrus and Voodoo Banshee display adapters (when ready,
this code should return the VESA EDID for the Bochs plug&play monitor).

ca9120655b Some work on the Voodoo Banshee emulation.
- Moved basic BitBlt stuff from the Cirrus code to a separate header file to
  make it usable for the Voodoo Banshee, too.
- Rewrite of the screen-to-screen BitBlt code for the new ROP code.
- Calculate redraw parameters based on the screen start.
- Set "Banshee busy" bit in the status register when 2D is busy.
- Added some error messages for unimplemented features.

5ec78eaae2 Modified VGA extension init method. Now it returns 1 if the extension code has
initialized the VGA compatible video memory. If it has returned 0 the VGA core
code sets up the default VGA memory (256k).

610cec209d Rewrite of the VGA/Cirrus code to reduce code duplication.
- Moved VGA timer handler to the VGA core and handle the non-VGA case there.
  It calls the specific update() code and finally bx_gui->flush().
- Moved the VGA update frequency parameter handler and the refresh_disply()
  method to the VGA core.
- Store the VGA extension parameter in the VGA core.
- Voodoo: Fixed graphics snapshot.

d46a9b7205 Some work on the PCI devices code.
- Since the pci_read_handler() method is identical in most devices, move it
  to the base class to reduce code duplication. Only the 'pcidev' device has
  it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.

9933ffa3d9 vga refresh framework changes
- renamed trigger_timer() methods to refresh_display()
- new argument 'redraw' added to force a refresh of the entire screen
  (used in snapshot mode)
- siminterface method refresh_vga() now checks if the Bochs gui init is complete
- use SIM->refresh_vga() in some more cases

4eae421272 Graphics snapshot feature re-implemented for the new graphics API
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
  Voodoo adapter possible

1fd6745aea Started rewrite of the gui code to make the graphics snapshot independent from
the display adapter code. When ready, the common gui code should handle it
completely. The snapshot handler should set a flag 'snapshot_mode' and then it
should force a display update. The graphics update code should be redirected to
some code that 'draws' to a snapshot buffer. These first steps are done:

- store some guest display settings in the gui code (text / graphics switch,
  x / y resolution and bpp)
- split 8 bpp palette update code in a common and a specific part and store the
  palette values in the gui code
