This set introduces some tracing facilities to rtla tools.
It adds the possibility to change the tracing_thresh to osnoise,
allowing a fine tune of OS noise detection.
It also adds the auto tracing feature (-a threshold us), which aims
helping the first approach to a problem by setting common tracing
features with a single parameter.
Finally, it also allow osnoise top and timerlat top to enable additional
trace events via (possible multiple) -e sys:event options.
