58019a1649 Renamed "ltdl.h" to "ltdl-bochs.h" to avoid conflicts with the include file
that is a part of the libtool package. Updated Makefile dependencies.
TODO: check if we can get rid of the ltdl*.* files (this would be possible if
the ltdl library is always available if libtool is present).

f3a6fbd235 Simplified setup of special runtime menus / dialogs
- If the runtime flag of a bx_list_c object is set, all it's items are set up
  as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
  each single parameter is no longer needed.

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

bdf28d89dd Graphics snapshot handling for standard VGA and compatible modes (old graphics
API) moved to the gui code. Splitted graphics_tile_update() in a common and a
specific part. The common part handles the snapshot case if active. As a side
effect, the snapshot feature now works for CGA modes, too. Fixed palette colors
in 8 bpp snapshots.

Volker Ruppert
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

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.
