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.

5045a241e8 - ported Intel(R) 82540EM Gigabit Ethernet adapter emulation from Qemu
- TODO: add save/restore support, use Bochs function for host to little endian
  data conversion, timers of networking modules 'vnet' and 'slirp' should use
  the device speed instead of fixed 10 MBit

1b9f286945 - New way of CPUs scheduling in SMP mode brings up to 50% speedup to the
SMP emulation. New implementation uses dynamic CPU quantum value and takes
   full advantage of the trace cache. Each emulated processor will execute
   the whole trace before switching to the next processor.
 * It is also safe to use large (up to 16 instructions) quantum values for
   the SMP emulation now and improve performance even further.

The same merge also completely fixes SF bug :
  [3312237] stepN command might be not working properly

Handlers chaining speedups are also supported with SMP emulation now.

cb261c45d3 removed non-working code for z-unodable and z-volatile images.
our priority is to implement support for std disk image formats (VMDK, VDI) instead.

13feb0772a - 10% emulation speedup with handlers chaining optimization implemented. The
feature is enabled by default when configure with --enable-all-optimizations
    option, to disable handlers chaining speedups configure with

d11114ac19 Patch for emulating target with larger memory than host has available by Gary Cameron.
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.

76c11e1a40 - Configure option --enable-acpi is deprecated and should not be used anymore.
The ACPI support is always automatically compiled in if PCI is compiled in.
    The ACPI still could be disabled using .bochsrc 'plugin_ctrl' option.

Updated CHANGES and docs as well.

e6d56f97ae - renamed bas class for lowlevel sound support to bx_sound_lowlevel_c

  independent from the presence of the SB16 emulation

ae45908060 - ported ES1370 soundcard emulation from Qemu. For now, only sound output to
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

8c32359615 The VBE display extension is now a part of the Bochs core. The configure option
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.

49f4a38c82 - applied user mode networking patch by Heikki Lindholm. It requires the most
recent version of Slirp with Debian patches applied. On a Linux host the
  guest OS can access the internet without running Bochs with root privileges.
  TODO:
  * rewrite the DHCP part of eth_vnet.cc that it can be used here, too
  * Slirp doesn't compile on 64-bit Linux with GCC 4.5
  * WIN32 is not supported yet

dec6bcaf73 - started separation of sb16 and lowlevel sound module code. The first step is
an own header file for the basic sound output class. When ready we should
  have a separate 'soundmod' plugin that could be used by other soundcard
  implementations.
