Add two user events for AUX area tracing. PERF_RECORD_AUXTRACE_INFO contains metadata, consisting primarily the type of the AUX area tracing data plus some amount of architecture-specific information. There should be only one PERF_RECORD_AUXTRACE_INFO event. PERF_RECORD_AUXTRACE identifies AUX area tracing data copied from the mmapped AUX area tracing region. The actual data is not part of the event but immediately follows it.
