perf kvm: Introduce histograms data structures
This is a preparation to support histograms in perf kvm tool. As first
step, this patch defines histograms data structures and initialize them.
Committer notes:
Those are only used by functions enclosed in:
#if efined(HAVE_KVM_STAT_SUPPORT) && defined(HAVE_LIBTRACEEVENT)
So do this for these new functions and struct as well.
