da42a100eb - major rewrite of the vga / cirrus code
- added new class bx_vgacore_c containing the core of the standard VGA
    emulation. This is now the base class for both vga and cirrus.
  - created 2 separate plugins 'vga' (for standard VGA and VBE) and 'svga_cirrus'
    (Cirrus emulation). The vga extension option is used to select which plugin
    should be loaded.
- TODO: move the pcivga code to the VGA/VBE code, add subdirectory for display
        adapters, severak improvements and cleanups
