73c914a7f6 - Some work on the Voodoo Graphics emulation (Voodoo2 specific) 
- prepared hRetrace value implementation (cannot be enabled yet, since the
    driver passes this test and gets confused in next stage (segfault).
  - Detect CMDFIFO access (not present yet).
  - Report disabling Voodoo graphics mode.
  - TODO #1: Fix Voodoo2 to make it usable.
  - TODO #2: Split update code and drive gui screen updates from the VGA timer
    (finally remove new realtime option again).

5f5d8e2c33 Applied initial version of the 3dfx Voodoo Graphics emulation. The Voodoo core 
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
