0050f7aa18 perf evlist: Introduce evlist__for_each() & friends
For the common evsel list traversal, so that it becomes more compact.

Use the opportunity to start ditching the 'perf_' from 'perf_evlist__',
as discussed, as the whole conversion touches a lot of places, lets do
it piecemeal when we have the chance due to other work, like in this
case.

046625231a perf tools: Introduce zfree
For the frequent idiom of:

   free(ptr);
   ptr = NULL;

Make it expect a pointer to the pointer being freed, so that it becomes
clear at first sight that the variable being freed is being modified.

d53e57d039 perf ui tui progress: Don't force a refresh during progress update
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

accessing it directly.

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

53805eca3d perf tools: Remove cast of non-variadic function to variadic
The 4fb71074a5 (perf ui/hist: Consolidate hpp helpers) cset introduced
a cast of percent_color_snprintf to a function pointer type with

cast.

The symptom of this was all percentages being reported as 0.00% in perf

Following commit tightened up the buffer size for output to strict width

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.
