rtla: Add osnoise tool
The osnoise tool is the interface for the osnoise tracer. The osnoise
tool will have multiple "modes" with different outputs. At this point,
no mode is included.
The osnoise.c includes the osnoise_context abstraction. It serves to
read-save-change-restore the default values from tracing/osnoise/
directory. When the context is deleted, the default values are restored.
It also includes some other helper functions for managing osnoise
tracer sessions.
With these bits and pieces in place, we can start adding some
functionality to rtla.
