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.
