  Modified files:
    sys/ia64/ia64        db_trace.c unwind.c 
    sys/ia64/include     unwind.h 
  Log:
  Add logic to trace across/over a trapframe. We have ABI markers in
  our unwind information for functions that are entry points into the
  kernel. When stepping to the next frame, the unwinder will let us
  know when sych a marker was encountered. We use this to stop the
  current unwind session, query the trapframe and restart a new
  unwind session based on the new trapframe.
  
  The implementation is a bit sloppy, but at this time there are
  bigger fish to fry.
