We want to include events with metadata, like context switches, and this requires the API to handle events with payloads (e.g. information about such context switches). Besides this, we want to support multiple similar events between two consecutive instructions, like multiple context switches. However, the current implementation is not good for this because we are defining events as bitmask enums associated with specific instructions. Thus, we need to decouple instructions from events and make events actual items in the trace, just like instructions and errors. - Add accessors in the TraceCursor to know if an item is an event or not - Modify from the TraceDumper all the way to DecodedThread to support - Renamed the paused event to disabled. - Improved the tsc handling logic. I was using an API for getting the tsc from libipt, but that was an overkill that should be used when not processing events manually, but as we are already processing events, we can more easily get the tscs. event items. Fortunately this simplified many things - As part of this refactor, I also fixed and long stating issue, which is that some non decoding errors were being inserted in the decoded thread. I changed this so that TraceIntelPT::Decode returns an error if the decoder couldn't be set up proplerly. Then, errors within a trace are actual anomalies found in between instrutions.
