perf tools: Finish the removal of 'self' arguments

2013-11-05T18:32:36Z

They convey no information, perhaps I was bitten by some snake at some point, complete the detox by naming the last of those arguments more sensibly.

perf scripts python: Add a python library EventClass.py

2012-08-08T15:53:08Z

This library defines several class types for perf events which could help to better analyze the event samples. Currently there are just a few classes, PerfEvent is the base class for all perf events, PebsEvent is a HW base Intel x86 PEBS event, and user could add more SW/HW event classes based on requriements.
