Introduce a new perf_ioctl command to change the OA configuration of the active stream. This allows the OA stream to be reconfigured between batch buffers, giving greater flexibility in sampling.

Original patch for dynamic reconfiguration by Lionel Landwerlin. Signed-off-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@xxxxxxxxx>
