  Log:
  Fix the handling of the UCS_RXSTOP flag so that it always tracks
  whether or not the receive pipe is stopped. This ensures that we
  do not attempt to start the same transfer twice, and it allows
  ucomstop() to skip the restarting of the read pipe if it was not
  originally running, such as when called indirectly from ucomreadcb().
