Patches 2 and 3 are in tools/lib and need to go through Jiri and
Arnaldo. Please repost them again. I can give them acks.

No need, I can pull them from here. I just been a bit busy to do so.

Actually, libtraceevent does not exist in trace-cmd, just the event
parsing code. libtraceevent needs to be packaged up and supplied as a
library. That's on our todo list, but never seems to get done :-/

Until libtraceevent is provided by all distros, there will continue to
be duplicate code. And it's not just with these two tools. I can think
of two other tools that also share this code for parsing. It really
does need to get packaged up.
