Subject: [PATCH 08/25] perf evsel: Move xyarray.h from evsel.c to evsel.h to reduce include dep tree

From: Arnaldo Carvalho de Melo <acme@...hat.com>

All we need in util/evsel.h is the foward declaration of 'struct
xyarray', not the internal/xyarray.h, that can be moved to util/evsel.c
and then we reduce the header dependency tree.
