c05cb5e1d7 Removed legacy "load32bitOShack" feature. In the early days of Bochs some hacks
were required to load a 32 bit OS. In the meantime Bochs has been made capable
of loading 32 and 64 bit OS's without hacking.

db95a54238 Prepared config interface for a hard disk sector size option.
This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,
TODO: hdimage and bximage code, harddrv and USB disk emulation, BIOS.

e187f3907a Removed Voodoo realtime option. Since the gui screen update timing is now
controlled by the 'vga' option and Voodoo2 CMDFIFO thread has the best
performance with realtime mode disabled, this option is now obsolete.

realtime option (enabled by default).

8d1e3b2ac1 Added statistics collection infrastructure in Bochs and
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

dd794d6d44 Some more work on the 'sound' bochsrc option
- added 'wavein' parameter to specify the wave input device if necessary
 - if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
 - SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
 - TODO: implement 'wavemode' feature for ES1370 similar to SB16

192aa1f369 Added global sound control option in bochsrc and config interface
- added 'sound' option to select the driver and the wave output device
  (see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
  wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly

75bda1d5cd implemented SVM emulation support for Bochs (incomplete yet)
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.

Also looking for anybody with existing SVM kernels - as simple as possible - for testing.

Status:
 - exceptions intercept is not implemented yet
 - IO intercept is not implemented yet
 - MSR intercept is not implemented yet
 - virtual interrupts are not implemented yet
 - CPUID is not implemented yet

No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.

62d0c8abf7 - Now you could disable x86-64 from .bochsrc so now it is possible to emulate
32-bit CPU using Bochs binary compiled with x86-64 support.

The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.

44241a1e56 - Added support for AVX and AVX2 instructions emulation, to enable configure
with --enable-avx option. When compiled in, AVX still has to be enabled
    using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.

  - Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
    instructions support can be enabled using .bochsrc CPUID option.

1a051f9f00 Added several predefined CPUs that can be selected from .bochsrc using new CPU::MODEL option.
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

168efb7710 - re-implemented USB port options parameter to assign specific options to the
connected device. For now this feature is only used by the 'disk' device to
  specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
  The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
  timer() methods of all hubs. This makes sure that all parameters for the
  device have been set at connect time. TODO: this technique could also be used
  for the floppy and cdrom media change.

8b46dcfc0b - added parameter to control the floppy media write protection. This is based on
the SF patch #1539417, but rewritten from scratch (patch too old). Differences
  to the original version:
  * internal parameter name "readonly"
  * update parameter if floppy image is readonly
  * wxWidgets support
  * documentation updates
  * no specific toolbar buttons

ee131a7471 - new implementation of the win32 runtime dialog based on the start menu dialog
* removed old win32 runtime config dialog since the property sheet isn't
    compatible with the win32 ParamDialog
  * reorganized runtime parameter lists (usb and cdrom setup in device init)
  * renamed win32 StartMenuDialog() to MainMenuDialog() and some related name
    changes
  * added runtime support to the MainMenuDialog
- win32 start/runtime menu: set keyboard focus to the start/continue button
- win32paramdlg: SetParamList() now checks for list size changes to avoid crash
