Print accumulated stat of a hist entry if requested.

To do that, add new HPP_PERCENT_ACC_FNS macro and generate a
perf_hpp_fmt using it.  The __hpp__sort_acc() function sorts entries
by accumulated period value.  When accumulated periods of two entries
are same (i.e. single path callchain) put the caller above since
accumulation tends to put callers on higher position for obvious
reason.

Also add "overhead_children" output field to be selected by user.

accumulated entry should be added to ->stat_acc but not ->stat. Add

There're some duplicate code when adding hist entries.  They are
different in that some have branch info or mem info but generally do
same thing.  So introduce new struct hist_entry_iter and add callbacks
to customize each case in general way.

The new perf_evsel__add_entry() function will look like:

  iter->prepare_entry();
  iter->add_single_entry();

  while (iter->next_entry())
    iter->add_next_entry();

  iter->finish_entry();

This will help further work like the cumulative callchain patchset.

The -F/--fields option is to allow user setup output field in any

  overhead, overhead_sys, overhead_us, sample and period

If guest profiling is enabled, overhead_guest_{sys,us} will be

the output field list automatically.

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).

The hist_browser__reset() is only called right after a filter is

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.

By turning the addr_location->filtered member from a boolean to a u8
bitmap, reusing (and extending) the hist_filter enum for that.

This patch doesn't change the logic at all, as it keeps the meaning of
al->filtered !0 to mean that the entry _was_ filtered, so no change in
how this value is interpreted needs to be done at this point.

This will be soon used in upcoming patches.

Add support for recording and displaying the transaction flags.
They are essentially a new sort key. Also display them
in a nice way to the user.

Extend the perf branch sorting code to support sorting by in_tx
or abort_tx qualifiers. Also print out those qualifiers.

This also fixes up some of the existing sort key documentation.

We do not support no_tx here, because it's simply not showing
the in_tx flag.

Moving hist_entry__period_snprintf function into stdio code and making
it static, as it's no longer used anywhere else.

Moving diff related columns into diff command, because they are not used
by any other command.

Also moving the column entry functions under generic one with baseline
as an exception.

Adding 'struct perf_hpp_fmt' into hpp callbacks, so commands can access
their private data.

It'll be handy for diff command in future to be able to access file
related data for each column.

The --percent-limit option is for not showing small overhead entries in
the output.  Maybe we want to set a certain default value like 0.1.

Those _threaded() functions are needed to make hist tree handling
thread-safe, but AFAICS the only thing it does is forcing it to use
the intermediate 'collapsed' tree.

This can be acheived by setting sort__need_collapse to 1 in cmd_top() so
no need to keep those _threaded() variants.
