Hi,

This is a cleanup and refactoring patchset for the hist printing code
by adding perf_hpp__format functions and perf_hpp.  I believe it makes
the code easy to maintain and to add new features like upcoming group
viewing and callchain accumulation.

Any comments are welcome, thanks.
Namhyung

v3 -> v4:
 * Rebase to current acme/perf/core
 * The first two in the previous series have been merged
 * Rename hist_period_print to perf_hpp_fmt (Arnaldo)
 * Rename ctx->s to hpp->buf (Arnaldo)

v2 -> v3:
 * Move fprintf code to ui/stdio/hist.c (Arnaldo)
 * Add ack from Pekka

From: Namhyung Kim <namhyung.kim@lge.com>

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.

From: Namhyung Kim <namhyung.kim@lge.com>

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.

Override hpp->color functions for TUI. Because line coloring is done
outside of the function, it just sets the percent value and pass it.
