Just like the old perf top --tui and the --stdio version.
But because we have the initial menu to choose which event to show in a
session with multiple events we can see how many chunks were lost in
each of the event types, clarifying which events are being affected the
most.

We were doing parts of it in hists__collapse_resort and parts of it in
hists__output_resort, leading to a bogus total_period.
Fix it by doing just the filtering operation when collapsing because
there we know that the Zoom operations adds filters just what is in
hists->entries, not to the new batch of entries being collapsed.
And move all the nr_entries + total_period recalculation to
hists__output_resort since we will traverse all entries anyway there.
Problem introduced when developing threaded addition of new batches
of hist_entries, i.e. post v3.1.

For instance, on Fedora 8:
CC /home/acme/git/build/perf/util/header.o
cc1: warnings being treated as errors
util/header.c: In function ‘write_cpudesc’:
util/header.c:281: warning: implicit declaration of function ‘getline’
util/header.c:281: warning: nested extern declaration of ‘getline’
make: *** [/home/acme/git/build/perf/util/header.o] Error 1
make: Leaving directory `/home/acme/git/linux/tools/perf'
[acme@localhost linux]$
This happens due to header ordering, in perf util.h sets _GNU_SOURCE, so
it must come first.

No need to unblock it at each ui__getch() and also allow other users to
check if a resize is needed, or force an refresh of terminal dimensions.
The 'force' one shouldn't be needed, but its in a slow path, so leave it
like that for now, I'll revisit this another day.

The __perf_evsel__open routing was grouping just the threads for that
specific events per cpu when we want to group all threads in all events
to the first fd opened on that cpu.
So pass the xyarray with the first event, where the other events will be
able to get that first per cpu fd.
At some point top and record will switch to using perf_evlist__open that
takes care of this detail and probably will also handle the fallback
from hw to soft counters, etc.

Fglrx propietary driver has symbol names over 128 chars (:S). This
breaks the function kallsyms__parse.
This fix increases the size of KSYM_NAME_LEN, so kallsyms__parse can
work on such kernels.
The only counterparty, is that such function requires 128 more bytes to
work.

Fixing the way the tracing information is stored within record command.
The current implementation is causing issues for pipe output.
Following commands fail currently:
perf script syscall-counts ls
perf record -e syscalls:sys_exit_read ls | ./perf report -i -
The tracing information is part of the perf data file. It contains
several files from within the tracing debugfs and procs directories.
Beside some static header files, for each tracing event the format
file is added. The /proc/kallsyms file is also added.
The tracing data are stored with preceeding size. This is causing some
dificulties for pipe output, since there's no way to tell debugfs/proc
file size before reading it. So, for pipe output, all the debugfs files
were read twice. Once to get the overall size and once to store the
content itself. This can cause problem in case any of these file
changed, within the storage time.
To fix this behaviour and ensure the integrity of the tracing data, we:
- read debugfs/proc file into the temp file
- get temp file size and dump it to the pipe
- dump the temp file contents to the pipe

Following the 'perf report' model we don't zap hist_entry instances from
the rb tree, we just keep them with he->filtered set to a mask of the
filters applied to it (thread, parent, DSO so far).
In top we need to decay even filtered entries, but we better not touch
total_period for them...
Now everything seems to work when filters are applied on top as they
worked in 'report', i.e. both dynamic and static hist entry browsing
works with filters.

Feature bitmap is declared as an array of unsigned longs -- not good
since its size can differ between the host that generated the data file
and the host analyzing the file.
We need to handle endianness, but we don't know the size of the unsigned
long where the file was generated. Take a best guess at determining it:
try 64-bit swap first (ie., file created on a 64-bit host), and check if
the hostname feature bit is set (this feature bit is forced on as of
fbe96f2). If the bit is not, undo the 64-bit swap and try a 32-bit
swap. If the hostname bit is still not set (e.g., older data file), punt
and fallback to the original behavior -- clearing all feature bits and
setting buildid.

The selection and scroll bar are really needed only when the user starts
navigating, before that it just provide distractions.
This also brings the initial screen to look more like the stdio UI,
which more people are used to.
The new code is flexible enough that menu like browsers can opt out and
start with those UI elements.

We were not recognizing 'E' as a hotkey due to a bug introduced when
switching to the new, hist_entry based top. Fix it by returning that 'E'
is mapped if evlist->nr_entries > 1.

The readlink function doesn't guarantee that a '\0' will be put at the
end of the provided buffer if there is no space left.
No need to do "buf[len] = '\0';" since the buffer is allocated with
zalloc().

Its becoming common to allow the user to filter out parts of the data
structure being browsed, like already done in the hists browser and in
the annotate browser in the next commit, so provide it directly in the
ui_browser class list_head helpers.
More work required to move the equivalent routines found now in the
hists browser to the rb_tree helpers.

With underlying dynamic data structures we need to invalidate pointers
to them after a timer, as that entry may have vanished (decayed in top,
for instance).
I forgot about browser_ui->top. Fix it by resetting it to null after a
timer. The seek operation from SEEK_SET will then set it to a valid
entry because it starts from rb_first(&hists->entries).

When using multiple events the 'top' and 'report' tools will first
present the user with a menu to choose the event to browse.
After that the user can either press <- to go back to the menu and
choose another event or instead press TAB to go the next event without
having to go back to the menu or shift-TAB (UNTAB) to go the previous
event, useful to quickly visually see if multiple events are correlated.
The handling of each hists browser return was broken by the ed7e566,
that combined both switches, the first that was for choosing the event
and the second that was for checking if switching to the next event
without passing thru the events menu.
Repeat with me: Don't be clever like that.
Fix it by moving the switch to right after the call to the hists
browser, making abundantly clear that the two switches are unrelated.
This also fixes a compiler warning about the 'pos' variable being
possibly used unitialized.

We were removing only when using a --sort order that needs collapsing,
while we also use it in the threaded case, causing memory corruption
