7ca95178b0 - fixed save/restore in VBE mode. The class bx_shadow_bool_c expects bit #0 to 
be set for "true", but variable "lfb_enabled" wasn't correctly set up.
- TODO: check the whole Bochs code for the correct usage of variables saved
  with bx_param_bool_c.

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.
