NACK, this semantic change is not backwards compatible - this will break
all applications & language bindings currently using libvirt perf events.

In addition "reset" is not really a state - "enabled" / "disabled" are
stats - 'reset' is an action that is applied to an existing state. So
modelling 'reset' as a state is wrong too IMHO.

Daniel
