The problem with relying on a plugin is that every userspace application
(currently two that I am aware of: perf and trace-cmd) has to add
special-case kvm code to work around our crappy format.
Move the plugins to tools/trace-formats and install them in
/lib/modules/$(uname -r)/tracepoint-formats/*.so.
With these patches we at least get back to an event format that is
self-describing - no plugin necessary.
There will always be special cases. Look at how trace-cmd formats the
kvm_emulate_insn event.
