This set introduces some tracing facilities to rtla tools:
- Add the possibility to change the tracing_thresh to osnoise,
allowing a fine tune of OS noise detection.
- Add 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.
- Add -e/--event option, allowing osnoise and timerlat to
enable additional trace events via (possible multiple)
-e sys:event options.
- Add the --filter option to filter the previous -e event.
- Add the --trigger option to allow the usage of tracing
trigger of the previously set -e event. If the trigger
is hist: one, rtla automatically saves the hist file
associated with the -e event.
Depends on "rtla: Some RTLA fixes for 5.17":

Changes from V1:
- Add -e to osnoise/timerlat hist
- Add --trigger
- Add --filter
- Add support to save hist file
- Function name refactoring
