for watching the log output at simulation time. This feature has been prepared
and described in the code (BX_ASYNC_EVT_LOG_MSG), but it was never implemented.
A viewer window could be implemented easily in wx. The gui debugger could also
have an option to view the log output while debugging.
- moving ToggleMouse() call to the gui thread fixes two issue: possible deadlock
in wxGTK after showing message box, mouse cursor not hidden in wxMSW
- don't add undefined toolbar events to the queue
- removed unused / unhandled cases from the toolbar code
- in wx we had two logfunctions for the siminterface (removed duplicate init)
- renamed siminterface prefix to "SIM"
- moved variable "pluginlog" to the plugin interface
- fixed / removed some forward declarations

- reverted changes in SVN revision 10985 (-DWIN32 now works again with Cygwin)
- don't link Bochs.exe or RFB gui with wsock32.dll in the Cygwin case
- the win32 gui doesn't need to be linked wsock32.dll at all
- added menu item for saving configuration
- use existing cdrom runtime menu instead of hardcoded items
- some code cleanups after cdrom option changes
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).

- process dependent lists only for a few control notification messages
- Added second try to find the control ID for a parameter (browse all lists)
- 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.
- use LibVNCServer macros for pthread mutex support in the keyboard / mouse code
- workaround for WIN32: use critical section stuff instead (not yet present in
LibVNCServer)
- don't quit simulation on client disconnect (reverted to original behavior)
- don't wait for client connection on startup if timeout is set to 0
- RFB color handling rewritten to fix headerbar and statusbar colors in 8 bpp
graphics modes (they no longer depend on VGA palette)

- minor other changes
- vncsrv: noclient mode: simulation run even without client connected
- vncsrv / rfb: parse specific options before starting server thread
- vncsrv / rfb: panic on invalid timeout value
- vncsrv: don't wait for client connection if timeout value is 0
- vncsrv / rfb: removed unnecessary newlines
- quit simulation if the client has disconnected
- moved update region checks to new function rfbAddUpdateRegion
- changed the order of methods and function in the file
- use the CXXFLAGS and link options provided by the libvncserver-config script
- added Windows support for MinGW/MSYS (compiles fine, but crashes sometimes)
higher resolutions and > 8 bpp graphics modes. The RFB gui with limited
capabilities is still available.

The Windows version looks almost stable, but the GTK version fails in some cases.
That's why the classic wx debugger is still available if BX_DEBUGGER_GUI is set to 0.
- added function close_debug_dialog() to handle the simulation stop case in wx
- disable all the wx debugger related code if BX_DEBUGGER_GUI is set to 1
- added enhanced debugger specific init code similar to the code in sdl.cc
- include debugger related resources on Windows

- use new methods in some parts of the code (TODO: win32 dialogs)
- check for the special value "none" to avoid failures
- moved 'user_shortcut' option to the keyboard option
- added new bx_param_c option value BOCHSRC_HIDDEN for parameters that should
only be available in the config interface. The new bochsrc option save and
parser function skip parameters with this flag set. This is useful for
parameters that will be set from the parser in a different way.
- save keyboard bochsrc line using the parameter list directly
- parse keyboard bochsrc options (except 'keymap') using the parameter list
- user shortcut: old-style syntax has already been removed
- increased minimum value for the keyboard's 'serial_delay'

- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used

- added new class bx_nonvga_device_c to make forwarding refresh requests to the
Voodoo adapter possible
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

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

- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
configuration when using the plugin name "*". The 'load' value 1 makes
sure that all plugins with the value 1 are loaded. The 'load' value 0
unloads all plugin with the value 0 (marked for removal).
- add the default set of plugins to the 'plugin_ctrl' list and load all these
pre-defined optional plugins before parsing the configuration.
- special wx case: verify plugin configuration before showing the plugin
control dialog and before initialising hardware.

realtime speed, even if it is out of sync.

Desription for CHANGES:
- Memory
- Added new configure option which enables RAM file backing for large guest
memory with a smaller amount host memory, without causing a panic when
host memory is exhausted (patch by Gary Cameron). To enable configure with
--enable-large-ramfile option.
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
