* Changed the interface of _kern_system_profiler_start(). The parameters are

passed in a structure now, so it is easier to extend it and ignore unused
  parameters.
* One can now select which system profiling events one is interested in.
* Added scheduling events to the system profiling interface. Those are pretty
  much the ones recorded when scheduler tracing is enabled. Still missing are
  the "wait object" events that allow to interpret what a thread is waiting
  for.
