Yeah, it can be useful to reuse existing code for extending the
functionality. But I'm not so sure including the plugin APIs into
libtraceevent is the right thing (at least in its current form).

And for this particular case in patch 2/2, it seems that format of the
kvm_emulate_insn event is broken already and should be fixed anyway.
Further improvement in this area can be addressed in perf kvm or other
users if needed.

So I'd like to hear from others.
Arnaldo and Steven, what do you think?

Thanks,
Namhyung
