  Log:
  Teach the stack trace code how to step across a double fault when stepping
  across frames.  Basically, if the current frame is for the
  'dblfault_handler' function, then get the next %eip and %ebp values to use
  from the original TSS of the thread that has the saved state when the
  double fault triggered.
