88a21d2f07 perf hists browser: Add back callchain folding symbol 
The commit 5395a04841 ("perf hists: Separate overhead and baseline
columns") makes the "Overhead" column no more the first one, this
caused the test that checks if it is time to show if a histogram
entry has callchains never hits.

Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD
instead of 0.

63a1a3d820 perf hists browser: Fix off-by-two bug on the first column 
The commit 5395a04841 ("perf hists: Separate overhead and baseline
columns") makes the "Overhead" column no more the first one.  So it
resulted in the mis-aligned column in the normal (non-diff) output.

b24c28f794 perf hists: Introduce struct he_stat 
The struct he_stat is for separating out statistics data of a hist
entry.  It is required for later changes.

It's just a mechanical change and should have no functional differences.

The total_period is available in struct hists data via the 'struct

output code path.

Removing 'struct perf_hpp::total_period' pointer, because it's no longer

Adding perf_hpp__column_enable function to enable/disable hists column

The diff command now enables/disables columns separately according to

columns are added into diff output.

5395a04841 perf hists: Separate overhead and baseline columns 
Currently the overhead and baseline columns are handled within single
function and the distinction is made by 'baseline hists' pointer passed
by 'struct perf_hpp::ptr'.

Since hists pointer is now part of each hist_entry, it's possible to
locate paired hists pointer directly from the passed struct hist_entry
pointer.

Also separating those 2 columns makes the code more obvious.

f9f526ecdc perf tools: Convert to GTK2_SUPPORT 
For building perf without gtk+2, we can set NO_GTK2=1 as a argument of
make.  It then defines NO_GTK2_SUPPORT macro for C code to do the
proper handling.  However it usually used in a negative semantics -
e.g. #ifndef - so we saw double negations which can be misleading.
Convert it to a positive form to make it more readable.

character including % sign (XX.YY%) so used "%5.2f%%" as a format
string.  However it might be the case if collapsing resulted in a single

will be shifted by 1 character.

1d037ca164 perf tools: Use __maybe_used for unused variables 
perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored

__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.

The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

ea251d51d2 perf hists: Introduce perf_hpp for hist period printing 
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.
