Moving the position calculation into the diff command, so the position
as prepared inside struct hist_entry data and there's no need to compute
in the output display path.

Removing 'displacement' from struct perf_hpp as it is no longer needed.

When a field separator is given, the output format doesn't need to be
fancy like aligning to column length, coloring the percent value and so
on.  And since there's a slight difference to normal format, fix it not
to break backward compatibility.

Current hist print functions are messy because it has to consider many
of command line options and the code doing that is scattered around to
places. So when someone wants to add an option to manipulate the hist
output it'd very easy to miss to update all of them in sync. And things
getting worse as more options/features are added continuously.

So I'd like to refactor them using hpp formats and move common code to
ui/hist.c in order to make it easy to maintain and to add new features.

Rename functions for consistency and move callchain print function
into hist_entry__fprintf().

Separate out those functions into ui/stdio/hist.c. This is required for
upcoming changes.
