8b96faf99e Some work on the timing code of the Bochs display adapters.
- Voodoo: Use the VGA/Cirrus timers to drive the gui screen update.
  The vertical retrace emulation is still driven by a separate timer.
- VGA/Cirrus: Since we are using the virtual timer, we also have to read
  time_usec() from it.
- vgacore: removed unused timer methods.

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

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.

f0afd30a9a Fixed Cirrus VGA PCI save/restore when a standard VGA mode is active. The PCI
memory setup doesn't depend on the mode and must always be done after restore.

401321d500 Added symbol BX_NULL_PREFIX and fixed textconfig log options table.
If log module name not specified, use device log prefix converted to lower
case as the name and simplified setting up some short prefixes.

fc4538a131 Some fixes / improvements in logging system
- fixed pluginlog init in non-plugin mode
- reduced logprefix length limit and use it for the related string parameter
- increase the device prefix size to 6
- TODO: change some more device prefixes

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
