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. We inject a
request into the OA context to reconfigure the stream asynchronou

One last thought for the interface, should we return the previous
config-id?
That limits the config-id space to long (min s32) so that we can report
