50dfe4b8de Some fixes for MSVC.
- Fixed compilation failure of MSVC plugin 'speaker'.
- Fixed some MSVC warnings.

e7093e74d8 Started implementing the i440BX PCI/AGP chipset.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
  but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
  secondary bus (AGP). Since this device must appear with device number #1 at
  the primary bus, it was required to change the PCI device numbers for the
  i440BX case. Moved the PIIX4 module to device number #7. The presence of the
  PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
  continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
  This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
  and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
  used for AGP when available.

89654a4beb Prepared devices and timer code for HPET support
- PIT / CMOS: added methods to control IRQ generation (for HPET legacy mode).
- Added method for activating timer with nanosecond value.
- Removed unused declaration in the keyboard code.
- TODO: virtual timer code also needs to handle nanosecond values.

9bc8651328 Extended functionality of class bx_shadow_data_c to simplify saving small byte
arrays. Changed register_state() code in a few devices to use this feature.
TODO: Use this feature in all devices with small byte arrays.

59f5a03af6 Rewrite of the virtual timer code to support both modes at the same timer.
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.

MSVC plugins)

27fdc3cd45 - added new parameter 'rtc_sync' for the 'clock' option. If this option is
enabled together with the realtime synchronization, the RTC runs at realtime speed.

aad2d89c83 - rewrite of the optional plugin control feature. Now the plugins are loaded
directly while parsing the bochsrc or command line. If plugin support is enabled,
  the option could load all optional plugins, not only the ones supported before.
  NOTE #1: The old option had all plugins enabled by default and gave the user
           a chance to diable them. Now the plugins are only loaded if they
           appear in the config line and they are set to "1".
  NOTE #2: Loading a plugin that is controlled by a bochsrc option is possible,
           but it currently leads to a panic, since the load command is still
           present in devices.cc.
  NOTE #3: The plugin init code creates the device object and registers the
           optional plugin device. As an option, it can create config parameters
           and register an option parser. The device init, register state and
           reset is still handled in devices.cc, but in the order the devices
           have been loaded with the plugin control.
  NOTE #4: If plugin support is disabled, the plugin control only accepts the
           devices listed in plugin.cc.
- plugin init of core plugins now fails if they are not loaded with the expected
  type. For core plugins the load order is important and they cannot be handled
  with the chained devices list (used for optional and user plugins).
- some additions for calling config.cc functions from a plugin device

071c5c1a26 A lot of changes but everything is really trivial.
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
