This requires some more work so that we can really just use the width of
current entries when we want to partition the screen.
Right now its just a prep patch so that we can have where to update
ui_browser->rows when introducing the column headers line, that will be
togglable, so we need to update it everytime we refresh the dimensions
of the browser.

The ui_browser->height is about the whole browser "window", including
any header, status lines or any other space needed for some "Yes", "No",
etc buttons a descendent browser, like hist_browser, may have.
Since the navigation is done mostly on the ui_browser methods, it needs
to know how many rows are on the screen, while details about what other
components are, say, if a header (that may be composed of multiple
lines, etc) is present.
Besides this we'll need to add a ui_browser->refresh_dimensions() hook
so that browsers like hist_browser can update ->rows in response to
screen resizes, this will come in a follow up patch.
This patch just adds ->rows and updates it when updating ->height, keeps
using ->height for the only other widget that can come with ui_browser,
the scrollbar, that goes on using all the height on the rightmost column
in the screen, using ->rows for the keyboard navigation needs.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
* Add --repeat global option to 'perf bench' to be used in benchmarks
such as the existing 'futex' one, that was modified to use it instead
of a local option. (Davidlohr Bueso)
* Fix fd -> pathname resolution in 'trace', be it using /proc or
a vfs_getname probe point. (Arnaldo Carvalho de Melo)
* Add suggestion of how to set perf_event_paranoid sysctl, to help
non-root users trying tools like 'trace' to get a working environment.
(Arnaldo Carvalho de Melo)
Fixes:
* Fix memory leak in the 'sched-messaging' perf bench test. (Davidlohr Bueso)
* The -o and -n 'perf bench mem' options are mutually exclusive, emit error
when both are specified. (Davidlohr Bueso)
* Fix scrollbar refresh row index in the ui browser, problem exposed now
that headers will be added and will be allowed to be switched on/off.
(Jiri Olsa)
Cleanups:
* Remove needless reassignments in 'trace' (Arnaldo Carvalho de Melo)
* Cache the is_exit syscall test in 'trace) (Arnaldo Carvalho de Melo)
* No need to reimplement err() in 'perf bench sched-messaging', drop barf().
(Davidlohr Bueso).
* Remove ev_name argument from perf_evsel__hists_browse, can be obtained
from the other parameters. (Jiri Olsa)

When cumulative callchain mode is on, we could get samples with
with no actual hits. This breaks the assumption of the annotation
code, that each sample has annotation counts allocated and leads
to segfault.
Fixing this by additional checks for annotation stats.

After output/sort fields refactoring, it's expensive
to check the elide bool in its current location inside
the 'struct sort_entry'.
The perf_hpp__should_skip function gets highly noticable in
workloads with high number of output/sort fields, like for:
$ perf report -i perf-test.data -F overhead,sample,period,comm,pid,dso,symbol,cpu --stdio
Performance report:
9.70% perf [.] perf_hpp__should_skip
Moving the elide bool into the 'struct perf_hpp_fmt', which
makes the perf_hpp__should_skip just single struct read.
Got speedup of around 22% for my test perf.data workload.
The change should not harm any other workload types.

The hists__filter_entries() function is called when down arrow key is
pressed for navigating through the entries in TUI. It has a check for
filtering out entries that have very small overhead (under min_pcnt).
However it just assumed the entries are sorted by the overhead so when
it saw such a small overheaded entry, it just stopped navigating as an
optimization. But it's not true anymore due to new --fields and
--sort optoin behavior and this case users cannot go down to a next
entry if ther's an entry with small overhead in-between.

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
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 nr_entries variable is increased inside the loop in the function
but it always count the first entry regardless of it's filtered or

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.

This will enable user to runtime switch the data file, when this option
is selected, it will popup all the legal data files in current working
directory, and the filename selected by user is saved in the global
variable "input_name", and a new key 'K_SWITCH_INPUT_DATA' will be
passed back to the built-in command which will perform the switch.
This initial version only enables it for 'perf report'.
v2: rebase to latest 'perf/core' branch (6e1d4dd) of acme's perf tree

When using event group viewer, it's better to show the group description
rather than the leader information alone.
If a leader did not contain any member, it's a non-group event.

Since we have all necessary information in the leader events and other
members don't, bypass members. Member events will be shown along with
the leaders if event group is enabled.

Move coloring logic into the hpp functions so that each value can
be colored independently. It'd required for event group view.
For overhead column, add a callback for printing 'folded_sign' of
callchains of a hist entry.

The hpp helpers do same job for each field so it was implemented as
macro in order to access those fields easily. But it gets cumbersome
to maintain a large function in a macro as the function grows. Factor
it out to a function with a little helper macro to access field.

Adding perf_hpp__list list to register and contain all period related
columns the command is interested in.
This way we get rid of static array holding all possible columns and
enable commands to register their own columns.
It'll be handy for diff command in future to process and display data
for multiple files.

David reported that current perf report refused to run on a data file
captured from a different machine because of objdump.
Since the objdump tools won't be used unless annotation was requested,
checking its presence at init time doesn't make sense.

Currently various hist browser functions receive 3 arguments for
refreshing histogram but only used from a few places. Also it's only
for perf top command so that it can be NULL for other (and probably
most) cases. Pack them into a struct in order to reduce number of those
unused arguments.
This is a mechanical change and does not intend a functional change.

As 'perf top' has no data files to run scripts against. Also add a
is_report_browser() helper function to judge whether the running browser
is for 'perf report'.
