- 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
