  Log:
  Add a facility in the CAM error handling code to retry selection timeouts.
  If the client requests that the error recovery code retry a selection
  timeout, it will be retried after half a second.  The delay is to give the
  device time to recover.
  
  For most of these drivers, I only added selection timeout retries where
  they were also retrying unit attention type errors.  The sa(4) driver calls
  saerror() in a number of places, but most of them don't request retrying
  unit attentions.
  
  Also, bump the default minimum CD changer timeout from 2 to 5 seconds and
  the maximum timeout from 10 to 15 seconds.  Some Pioneer changers seem to
  have trouble with the shorter timeout.
