Stanislav Shwartsman
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.

7bbfee58a2 - usually the realtime synchronization keeps the PIT-based system clock in sync 
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.

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

eb0c06f357 - added new parameter 'update_freq' for the 'vga' option that should replace the 
'vga_update_interval' option. The screen update frequency is still based on
  the emulated clock unless the realtime sync is enabled with the 'clock' option.
  TODO: rewrite the virt_timer code to support realtime screen updates
  independent from 'clock' setting.

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.

f57b14d338 Extended the interface of the fetch handler to general direct memory access handler. 
Now the handler receives 'rw' (BX_READ, BX_WRTE, BX_EXECUTE) access type as parameter.
If returning a pointer to <addr> - itr is assumed that whole 4K page containing the <addr> could be accessed using the same pointer with offset.
You can return a pointer for READ/WRITE only and disallow execute, this is handled properly in the CPU code.

92bb77ef1d Merge patch from SF tracker: 
[3298173] Breakpoint on VMEXIT event by Jianan Hao

Patch description:

The patch provides a new command "vmexitbp" to set breakpoint when VM guest exit. The simulation will be stopped before first HOST mode instruction is executed.

Usage:
Type "vmexitbp" in debugger command window to switch it on/off (similar to modebp).


Currently, the patch has no corresponding interface on GUI debugger. Someone may add it if interested.

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.

38ec72ece3 Merged serial port fix from [Bochs-developers] accessing COM1 via telnet. 
Upon investigation the problem is easily fixed in bx_serial_c::rx_timer_handler():

<snip>
   ssize_t bytes = read(socketid, &chbuf, 1);
#endif
   if (bytes)
   {
      BX_INFO((" -- COM %d : read byte [%d]", port+1, chbuf));
      data_ready = 1;
   }
<snip>

I think this means the extra check above will give no noticeable degradation of performance, so hopefully this can be applied to SVN.  It would avoid screwing up a running instance of Bochs when a remote network client unexpectedly disconnects from the COM1 tcp port.

Also some cleanup in serial.cc code.
