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
        --disable-handlers-chaining

002c86660a reword all the CPU code in preparation for future CPU speedup implementation. 
Bochs emulation can be another 10-15% faster using technique described in paper

9e723a044f - Added configure option to enable/disable A20 pin support. Disabling the 
A20 pin support slightly speeds up the emulation.

8065ada31f Some EIP setting cleanups. 
OK, currently I see big mess with setting of CS/EIP and SS/ESP everywhere, I have to unify it and make it easier !

d6f85c12f6 NMI support inside the CPU. 
Added two functions to query NMI and SMI from Bochs debugger.
In future they could be used for generating NMI or SMI by user request using GUI button (could be implemented separatelly later and under configure-time or .bocshrc option)

7b6c2587a9 Now devices could be compiled separatelly from CPU 
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...
