Kenneth D. Merry 50711c71c9 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.
