The definitions are in util.c so move the declarations to match.

<content type='text'>
perf_hpp__column_unregister() removes an entry from a list but doesn't
free the memory causing a memory leak spotted by leak sanitizer.

Add the free while at the same time reducing the scope of the function
to static.

<title>perf report: Allow specifying event to be used as sort key in --group output</title>

<id>urn:sha1:429a5f9d89fc52256b2a59cd1277afbfafb739b3</id>
<content type='text'>
When performing "perf report --group", it shows the event group
information together. By default, the output is sorted by the first
event in group.

It would be nice for user to select any event for sorting. This patch
introduces a new option "--group-sort-idx" to sort the output by the
event at the index n in event group.

For example,

Before:

  # perf report --group --stdio

  # To display the perf.data header info, please use --header/--header-only options.
  #
  #
  # Total Lost Samples: 0
  #
  # Samples: 12K of events 'cpu/instructions,period=2000003/, cpu/cpu-cycles,period=200003/, BR_MISP_RETIRED.ALL_BRANCHES:pp, cpu/event=0xc0,umask=1,cmask=1,
  # Event count (approx.): 6451235635

Now the output is sorted by the fourth event in group.

 v7:
 ---
 Rebase to latest perf/core, no other change.

 v4:
 ---
 1. Update Documentation/perf-report.txt to mention
    '--group-sort-idx' support multiple groups with different
    amount of events and it should be used on grouped events.

 2. Update __hpp__group_sort_idx(), just return when the
    idx is out of limit.

 3. Return failure on symbol_conf.group_sort_idx &amp;&amp; !session-&gt;evlist-&gt;nr_groups.
    So now we don't need to use together with --group.

 v3:
 ---
 Refine the code in __hpp__group_sort_idx().

 Before:
   for (i = 1; i &lt; nr_members; i++) {
        if (i == idx) {
                ret = field_cmp(fields_a[i], fields_b[i]);
                if (ret)
                        goto out;
        }
   }

 After:
   if (idx &gt;= 1 &amp;&amp; idx &lt; nr_members) {
        ret = field_cmp(fields_a[idx], fields_b[idx]);
        if (ret)
                goto out;
   }

So that we don't carry the session.h include directive in auxtrace.h,
which in turn opens a can of worms of files that were getting all sorts
of things via that include, fix them all.
