Until now the hpp and sort functions do similar jobs different ways.
Since the sort functions converted/wrapped to hpp formats it can do
the job in a uniform way.

The perf_hpp__sort_list has a list of hpp formats to sort entries and
the perf_hpp__list has a list of hpp formats to print output result.

To have a backward compatibility, it automatically adds 'overhead'
field in front of sort list.  And then all of fields in sort list
added to the output list (if it's not already there).

Moving towards sharing map groups within a process threads.

Because of this we need the map groups to be dynamically allocated. No
other functional change is intended in here.

Based on a patch by Jiri Olsa, but this time _just_ making the
conversion from statically allocating thread->mg to turning it into a
pointer and instead of initializing it at thread's constructor,
introduce a constructor/destructor for the map_groups class and
call at thread creation time.

Later we will introduce the get/put methods when we move to sharing
those map_groups, when the get/put refcounting semantics will be needed.

The hist_browser__reset() is only called right after a filter is
applied so it needs to udpate browser->nr_entries properly.  We cannot
use hists->nr_non_filtered_entreis directly since it's possible that
such entries are also filtered out by minimum percentage limit.

In addition when a filter is used for perf top, hist browser's
nr_entries field was not updated after applying the filter.  But it
needs to be updated as new samples are coming.

The --percentage option is for controlling overhead percentage
displayed.  It can only receive either of "relative" or "absolute".

"relative" means it's relative to filtered entries only so that the
sum of shown entries will be always 100%.  "absolute" means it retains
the original value before and after the filter is applied.

than double 0.0 so the remaining bits came from garbage.  The TUI and

Each call to tui_progress__update() would forcibly refresh the entire
screen.  This is somewhat inefficient and causes noticable flickering
during the startup of perf-report, especially on large/slow terminals.

It looks like the force-refresh in tui_progress__update() serves no
purpose other than to clear the screen so that the progress bar of a
previous operation does not subsume that of a subsequent operation.  But
we can do just that in a much more efficient manner by clearing only the
region that a previous progress bar may have occupied before repainting
the new progress bar.  Then the force-refresh could be removed with no
change in visuals.

This patch disables the slow force-refresh in tui_progress__update() and
instead calls SLsmg_fill_region() on the entire area that the progress
bar may occupy before repainting it.  This change makes the startup of
perf-report much faster and appear much "smoother".

It turns out that this was a big bottleneck in the startup speed of
perf-report -- with this patch, perf-report starts up ~2x faster (1.1s
vs 0.55s) on my machines.  (These numbers were measured by running "time
perf report" on an 8MB perf.data and pressing 'q' immediately.)

As the thread comm is going to be implemented by way of a more
complicated data structure than just a pointer to a string from the
thread struct, convert the readers of comm to use an accessor instead of
accessing it directly.

The accessor will be later overriden to support an enhanced comm
implementation.

[ Fixed up some minor const pointer issues ]

The 4fb71074 (perf ui/hist: Consolidate hpp helpers) cset introduced
a cast of percent_color_snprintf to a function pointer type with
varargs.  Change percent_color_snprintf to be variadic and remove the
cast.

The symptom of this was all percentages being reported as 0.00% in perf
report --stdio output on the armhf arch.

Following commit tightened up the buffer size for output to strict width
of used format columns:

  99cf666c perf hists: Fix formatting of long symbol names

This works fine until you hit color overhead output which places extra
bytes into output buffer. We need to account for color overhead in the
output buffer. Adding maximum color byte size to the output buffer size.

That will ease using a progress bar across multiple functions, like in
the upcoming patches that will present a progress bar when collapsing
histograms.

Based on a previous patch by Namhyung Kim.

Reserving 'struct ui_progress' to the per progress instances, not to the
particular set of operations used to implmenet a progress bar in the
current UI (GTK, TUI, etc).

The target address is provided by objdump and is not necessary a memory
address.  Add a helper to get the correct address.

When following a call, annotate_browser__callq() uses the current
symbol's map to look up the target ip.  That will not work if the target
ip is on a map with a different mapping (i.e.  start - pgoff is
different).

Separate out GTK codes to a shared object called libperf-gtk.so.  This
time only GTK codes are built with -fPIC and libperf remains as is.  Now
run GTK hist and annotation browser using libdl.
