Adrian Hunter a16ac0233e perf tools: Add user events for AUX area tracing
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.
