c28c7f6a06 Supply real VMX capabilities together with the CPU MODEL .bochsrc option. 
So now the same single option will choose not only the CPUID flags but also VMX capabilities matching real HW machine.

Removed cpuid of core2_extreme_x9770 from the cpudb. I don't remember its VMX capabilities anyway.
There is another Penryn model in the cpudb - core2_penryn_t9600.

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.

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.
