Once decoded from trace packets information on trace range needs
to be communicated to the perf synthesis infrastructure so that it
is available to the perf tools built-in rendering tools and scripts.

This patch adds support for complete packet decoding, allowing traces
collected during a trace session to be decoder from the "report"
infrastructure.

Add functionatlity to setup trace queues so that traces associated with
CoreSight auxtrace events found in the perf.data file can be classified
properly. The decoder and memory callback associated with each queue are
then used to decode the traces that have been assigned to that queue.

This patch adds the required interface to the openCSD library to support
dumping CoreSight trace packet using the "report --dump" command. The
information conveyed is related to the type of packets gathered by a
trace session rather than full decoding.

The auxtrace_info section contains metadata that describes the number of
trace capable CPUs, their ETM version and trace configuration, including
trace id values. This information is required by the trace decoder in
order to properly decode the compressed trace packets. This patch adds
code to read and parse this metadata, and store it for use in
configuring instances of the cs-etm trace decoder.
