These rules can be nested, for example, one can define a rule "dummy"
under "user" directory from the example above and this new rule will
be used for trace sources with the id string of "user/dummy".
For some STM hardware (e.g. ARM CoreSight STM), the masterID associated to a source is set at the hardware level and not user configurable. Since the masterID information isn't available to SW, introducing a new value of -1 to reflect this reality.
