Add Profiler object and fields. Add profiler extension API. It notifies Profiler objects with real-time performance data. Add module that implements the profiler extension. Add pw-profiler tool that binds to the profiler API and dumps the data into a log file, gnuplot files, a html page and a script to generate svg graphs. This is almost the same as what JACK2 JackEngineProfiling does.
