This patch adds a list structure to the decoder data to allow each decoded CoreSight ID to be associated with the callback context.
This allows the tracking of the source of the packets in the perf report -D command.
The code was contributed by Mike Leach in a separate commit which had to be adjusted and distributed across several patches.
