08f958f458 Fixed pageWriteStampTable to handle BIOS code as well - increased the table to all 4G instead of allocated memory size 
Avoid checking of pageWriteStamp in the heart of cpu loop with trace cache - now decWriteStamp will post stopTraceExecution event if it hits code page

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

082eb05b6b First step to fully configurable CPUID 
- put CPUID functions data into array, in future we could load this array from configure file
 - cpuid initialize function is more flexible now but still reuire some work

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

3ab94305a0 1. Fixed bug report 
[ bochs-Bugs-1562172 ] TLB_init() fails to initialize priv_check array if USE_TLB 0
2. Paging is always exists for i386+
   To disable paging it is better to use normal model without special code, only by setting cr0.pg=0

5dd0d64b11 - several changes for restart support in wx (not yet complete) 
* don't initialize cpu specific parameters for the wx debugger if they already
    exist
  * separate siminterface method init_save_restore() added
  * old wx specific handling in quit_sim() removed
  * new bx_list_c method clear() deletes all parameters from the list
  * moved devices cleanup code from the pc_system to a new devices method exit()
  * pc_system init code now sets ticksTotal to 0
