0b79759b8d Fixed dispatch of events with auxiliary data for the new protocol version (5). 
Added bounds checking when reading (skipping) the metadata in front of trace file.

7efe89bacc Explicitly terminate runs of aux data blocks with a well-known "aux data terminal" event. Previously a null byte was used. Each aux data block would write the null. Subsequent blocks would overwrite the prior block's null, effectively pushing the null to the end of a run aux data. However, if a different event was traced in the middle of the run it too would overwrite the null and corrupt the stream. With an explicit terminal event, structure can be recovered regardless of any multiplexing. 
Serial numbers are no longer perscriptive (i.e. there can be gaps).

Normal trace events' headers are 50% smaller.

7fa2ad9332 Gaps can occur in event serial numbering when late connect happens because tail-tracing discards packets. When that happens, analysis stalls waiting for a serial number that never occurs. This case is detected by seeing what serial analysis is waiting for and if it is the same after some inertia, decide analysis was stuck. The previous inertia length was too small. Now it is bigger. Sorting of the rota also takes into account the wrap.

1150e2234f Tail-tracing (a ring-buffer of previously traced events) has resulted in holes in the serial numbering used to reconstruct event order when analyzing a trace stream. Previously the serials were always consecutive, but now that tail-tracing drops older packets of events, serial number holes can appear. To mitigate that, if the same serial number is still queued in the analysis rota after two updates, a hole is assumed and the expected serial number is adjusted.

aa40aea03e Ancient traces have no magic FourCC. We can say though that they definitely start with 01 00 00 00. So we'll use that as a FourCC to identfiy antique traces.

27c78d0d4b Over time the framework behind the analysis of traces has grown reactively and organically without little thought to structure. The monolithic class has been refactored to derive some structure that will ease future maintenance (and protocol changes in particular).
