Remove dump_cpu debugger function, CPI method and all related structures.
...
Extended 'info' command in debugger to have all functionality of dump_cpu if needed. Also param tree print always could be used !

During Bochs benchmarking I figured out that hostasm actually slow down the emulation ... so remove this ugly code which also doesn't help :)

A lot of changes but everything is really trivial.
...
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
