[PATCH 05/20] perf tool: Add hpp interface to enable/disable hpp column

Namhyung Kim

From: Jiri Olsa <jolsa@redhat.com>

Adding perf_hpp__column_enable function to enable/disable hists
column and removing diff command specific stuff 'need_pair and
show_displacement' from hpp code.

The diff command now enables/disables columns separately according
to the user arguments. This will be helpful in future patches where
more columns are added into diff output.
