Initial Breakpoint support:
* sim-main.h: (struct _sim_cpu): add cur_device field. Define cur_device values, breakpoint value, and SIM_ENGINE_HALT_HOOK * interp.c (sim_open): initialize cur_device * sky-engine.c (engine_run): use cur_device to set current_cpu * sky-libvpe.c (vpecallms_cycle): add check for breakpoint * sky-hardware.h: delete NUMBER_CPUS * sky-hardware.c (attach_devices): create a memory mapped comm area for GDB/SIM interactions misc: * sky-vu.c ({read,write}_vu_misc_reg): do default behavior for unknown regs instead of sim_io_error. MP reg is float (was missing cast).
