Ok, so I rebased it on top of my perf/core branch, adjusting some stuff
wrt recent patchkits from Namhyung (hist_entry__callchain_fprintf() is
no more, etc), and renaming that perf_hpp_list->{list,sort_list} to
->{fields,sorts} as Namhyung suggested and you agreed, it builds...

But perf top isn't showing the overhead column... there were some
changes to perf report in this patchkit to move some initializations...
will check there...
