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

[ 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
