- 'vpc' image mode: moved header check to a separate function that opens the
file, checks header/footer and returns disk type (if requested)
- implemented restore function for 'vpc' mode images
- gui: updated yes/no dialog message after saving state
- save/restore documentation update (TODO: developer doc)

- TODO: save state function for the remaining image modes, restore support
- save/restore: when saving binary data to a file, use the full parameter path
(except "bochs." prefix) as the file name to avoid overwriting duplicates
dummy parameter and it's save/restore handlers. Currently only the save
support is implemented and the specific save function is only written for
flat mode images (copies whole disk image file to the save/restore folder).
- TODO #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
save/restore folder)
- re-implemented siminterface method is_wx_selected() (the old one had been
renamed to has_debug_gui() which is something different now)
- don't use alarm() if the wx gui is selected and instead use the wxTimer based
code that already exists for wxMSW
Added a new event BX_ASYNC_EVT_QUIT_SIM that is posted from the simulation thread
to the gui thread and the "Bochs stopped" message box is shown there.
- TODO: Fix random freezes in wxGTK that seem to be caused by the "show ips"
feature. A async event like the one above could possibly fix this problem.

- added helper functions bx_read_image() and bx_write_image()
- TODO: use helper function for the other disk image modes
- 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.
- device plugins that have been loaded, but not configured now set their
plugin control value to 0. Added the plugin unload check before signalling reset.
- enh_dbg: fixed defined-but-not-used warnings
- siminterface: renamed 'wx_debug_gui' to 'bx_debug_gui' and updated comments
- TODO: remove the wx debugger and use the enhanced gui debugger instead

sends absolute x/y values
- USB tablet code prepared to use the new feature
- TODO: implement this feature for each gui (sdl, win32, wx, x, ...)

- TODO #1: win32.cc also shouldn't include vga.h
- TODO #2: replace BX_MAX_XRES / BX_MAX_YRES by variables that can be set
depending on the configuration

existing "iolight timer" code in the hard drive code. If an LED is registered
with the "auto-off" flag, the device only needs to turn on the LED to indicate
data transfer. The LED timer in the gui code turns it off after 0.5 seconds if
it is not actived by another transfer. Added this feature to all network
devices.
- TODO #1: implement this feature in the USB host controllers
- TODO #2: the unused timer in the hard drive code could be used for the
emulation of seek functions
plugins is implemented in bochsrc, these functions can be used to install
additional options from the devices code. Then the whole init / parse / save
code for this device can be moved from config.cc to the device plugin.
with the host time. After using a runtime config dialog or save and restore
simulation, this behaviour makes the PIT clock and the VGA update timer
running way too fast until it's back in sync. Now the elapsed time is stored
in the variable 'real_time_delay' and it is used to let the PIT clock run at
realtime speed, even if it is out of sync.
- fixed size entries in bitmap file header for 8 bpp
- bx_param_filename_c now uses the file extension from the initial value as
the default (if present)
- SIM->ask_filename() now uses the correct parameter type
- win32paramdlg AskFilename(): added filter for BMP files

- TODO: implement this feature in other display libraries and add a key repeat generator in the
keyboard code that uses the typematic values from the guest.
Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336
parameters (path + status) have been set. TODO: implement this feature for the floppy, too.
- call update_drive_status_buttons() from update_runtime_options() to reduce the number of calls.
Now call update_runtime_options() from the gui floppy / cdrom handlers after closing dialog.
The patch was posted in mailing list at Thu 6/16/2011.
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
* ported the read part of the Qemu vvfat block driver
* added win32 specific directory functions (required for MSVC)
* TODO: write support, FAT32 support, read MBR and boot sector from file
- siminterface: added helper method hdimage_get_mode()
- moved hdimage related stuff from harddrv.cc to the hdimage code
- changed hdimage related names

'sdl'. Now both display libraries can be compiled together and used with the
'show ips' feature. TODO: win32-specific 'show ips' timers for 'rfb' and 'wx'
to access non-static devices from static parameter handlers.

- now using simple string dialog for editing the filename of the text snapshot
There is a trick in MSVC is to turn on the -Gr compiler switch which tells MSVC to compile all functions using fastcall calling convention. This way you don't have to edit each function declaration. But certain functions must NOT be fastcall, and those are callbacks from Windows which are defined either as cdecl or stdcall. The entry point main() also has to remain cdecl.
Patch by Darek Mihocka
This code is untested and it should add support for these features:
* variable line offset
* cursor color, disable and blinking
* character blinking
* TODO: variable cursor size, line graphics, h/v pel panning, split screen
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
