The hists->nr_entries is counted in multiple places so that they can
confuse readers of the code. This is a preparation of later change
and do not intend any functional difference.
Note that report__collapse_hists() now changed to return nothing since
its return value (nr_samples) is only for checking if there's any data
in the input file and this can be acheived by checking ->nr_entries.

The existing hists__inc_nr_entries() is a misnomer as it's not only
increasing ->nr_entries but also other stats. So rename it to more
general hists__inc_stats().

It's not the part of logic of hists__inc_stats() so it'd be better to
move it out of the function.

Add hists__{reset,inc}_[filter_]stats() functions to cleanup accesses
to hist stats (for output). Note that number of samples in the stat
is not handled here since it belongs to the input stage.

When a filter is applied a hist entry checks whether its callchain was
folded and account it to the output stat. But this is rather hacky
and only TUI-specific. Simply fold the callchains for the entry looks
like a simpler and more generic solution IMHO.

Currently, accounting each sample is done in multiple places - once
when adding them to the input tree, other when adding them to the
output tree. It's not only confusing but also can cause a subtle
problem since concurrent processing like in perf top might see the
updated stats before adding entries into the output tree - like seeing
more (blank) lines at the end and/or slight inaccurate percentage.
To fix this, only account the entries when it's moved into the output
tree so that they cannot be seen prematurely. There're some
exceptional cases here and there - they should be addressed separately
with comments.

When a filter is used for perf top, its hists->nr_non_filtered_entries
was not updated after it removed an entry in hists__decay_entries().
Also hists->stats.total_non_filtered_period was missed too.

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
not; caused an off-by-one error.
It'd become a problem especially there's no entry at all - it'd get a
segfault during referencing a NULL pointer.

->nr_non_filtered_entries and hist_browser__update_nr_entries() since
it's now used for filtering as well.

From: Namhyung Kim <namhyung@kernel.org>
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.

When TUI hist browser expands/collapses callchains it accounted number
of callchain nodes into total entries to show. However this code
ignores filtering so that it can make the cursor go to out of screen.
Thanks to Jiri Olsa for pointing out a bug (and a fix) in the code.
