- bx_param_num_c: set the value returned from the handler.
- bx_param_string_c: set the new value after processing the handler.
- harddrv param handler: check lock state of cdrom and modify value if true.
- Force a status bar update after unregistering an item.
- Added status indicators for USB disk and cdrom.
- Handle USB device disconnect in the runtime config handler, too.
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.
- Beep thread now only started one per simulation.
- Added some more multithreading macros and use them in rfb, vncsrv and soundmod.

- After handling mouse motion event in relative mode, move the cursor back to
the window center (similar to other guis).
- feature implemented in the wxWidgets gui
- feature not required for legacy SDL (releases keys on focus change)
- removed duplicate code in keyboard.cc
- TODO: implement feature in the win32 gui if required
The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
the init code. Started with the SeeReg[] array values. Some other setting could
be added later. The parser code is based on the slirp config parser.
Slirp: fixed possible segfault if the value for a parameter is missing.
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
- added new symbol BX_WITH_SDL2 and prepared build system
- TODO #1: add new option --with-sdl2 to configure script
- TODO #2: add new file sdl2.cc (porting seems hard to do - writing from scratch
might be better)
- don't try to resize the simulation window if minimized (iconic)
- handle window size correction in the gui event handler and by calling
resize_main_window(FALSE), since fullscreen mode is not always required
- fixed screen flickering after entering fullscreen for the second time
- now using resize_main_window() directly for leaving fullscreen mode
- dimension_update() now only used for guest display mode change
- TODO: more testing to find cases that can make Bochs crash
- moved fullscreen mode enable/disable stuff to a new function
- now only use dimension_update() for leaving fullscreen mode
- fixed fullscreen issues in text mode
- TODO: check if guest display is too large and add a proper handling for this case
- changing from window mode to fullscreen and back now looks okay
- changing guest resolution in fullscreen mode now also works
- TODO #1: rewrite of the window / fullscreen code to avoid using dimension_update()
to toggle the internal mode
- TODO #2: add size checks in dimension_update() to avoid crash. We could panic
at this point or compress screen to desktop size.

- disable border of simulation window in fullscreen mode
- TODO #1: fix window sizes after leaving fullscreen mode
- TODO #2: add screen size checks to avoid crash
This fixes the floppy malfunction after restore and maybe other issues. The
buggy code failed to clear the DMA controller mask bits and the floppy DMA
requests never arrived at the CPU.
- device prefix size needed update, but now using log function name instead
- don't use overlapping strcpy() (increment pointer and one single strcpy())
- now using get_logfn_id() to simplify code

Switched back to the original gui macro naming for linking plugins.
rules can be built now (keyboard, pit, gameport, serial, vga, svga_cirrus,
hdimage, netmod, soundmod, usb_common). The generated DLLs are usable with the
BOCHS.EXE built with the IDE, but the nmake won't work at all yet.
- bx_param_string_c method isempty() didn't work for raw byte strings. Now using
it to check whether or not the current value matches the initial one. The
parameter handling of the network adapters now use this method to check if
the MAC address is already initialized to avoid incorrect BX_ERRORs.
- small documentation update
- added new class LogViewDialog based on the already removed DebugLogDialog
- log output is only sent to the viewer if visible to avoid performance trouble
- text buffer is limited to 48k, older lines are removed if necessary
- red text color is used for error and panic messages and black for others
- minor related code cleanups
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

- show selected mouse toggle method in toolbar help and message box
- added capability to start the simulation with the power button
- 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).

- DONE: OK button forces a media change
- TODO: set status and media type after browse button
win32ParamDialog changes:
- changed base IDs for dialog child items
- set enum and bool parameters only if modified
- several changes for the floppy dialog
wx floppy dialog now forces a media change by clicking OK (same as win32dialog)
wxdialog.cc: one more whitespace cleanup
wxdialog.h: removed unused members
- es1370: fixed wave file parameter name
- wx cdrom dialog: use the first item of the cdrom runtime parameter list

- 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

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'

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

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
