56dd9fe3d9 - 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

* fixed minor error from printf patch confusion (negation based on wrong word)
  * added helper function await_ide
  * changed lba calculation to not corrupt lba (for debugging and clarity)
  * added support for partial completions of ata_cmd_packet (never happens in
    the simulator, but happens all the time in hardware)
  * update atapi_request_sense and atapi_is_ready - based on FILO
  * correct an int 15 call that should have been int 0x15
  * trivial fix when BX_PCIBIOS and BX_ROMBIOS32 not defined
- implemented %X in bios_printf (patch by Sebastian)

Stanislav Shwartsman
071c5c1a26 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
