- fixed several MSVC compilation warnings

* MSVC doesn't support localized variables (e.g. valid inside of a 'for' loop
only). So we cannot use the variable 'i' with different types (unsigned / int)
in the reset() method.
* added some conversions from Bit64s to bx_bool

Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead

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)
