perf hists browser: Fix the number of entries for 'e' key
The 'e' key is to toggle expand/collapse the selected entry only. But the current code has a bug that it only increases the number of entries by 1 in the hierarchy mode so users cannot move under the current entry after the key stroke. This is due to a wrong assumption in the hist_entry__set_folding().
The commit b33f922651011eff ("perf hists browser: Put hist_entry folding logic into single function") factored out the code, but actually it should be handled separately. The hist_browser__set_folding() is to update fold state for each entry so it needs to traverse all (child) entries regardless of the current fold state. So it increases the number of entries by 1.
But the hist_entry__set_folding() only cares the currently selected entry and its all children. So it should count all unfolded child entries. This code is implemented in hist_browser__toggle_fold() already so we can just call it.

perf thread: Add accessor functions for thread
Using accessors will make it easier to add reference count checking in later patches.
Committer notes:
thread->nsinfo wasn't wrapped as it is used together with nsinfo__zput(), where does a trick to set the field with a refcount being dropped to NULL, and that doesn't work well with using thread__nsinfo(thread), that loses the &thread->nsinfo pointer.
When refcount checking is added to 'struct thread', later in this series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to check the thread pointer.

James Clark noticed that the recent 63df0e4bc368adbd ("perf map: Add accessor for dso") patch accessed map->dso before the 'map' variable was NULL checked, which is a change in logic that leads to segmentation faults, so comb thru that patch to fix similar cases.

perf map: Add accessor for dso
Later changes will add reference count checking for struct map, with dso being the most frequently accessed variable. Add an accessor so that the reference count check is only necessary in one place.
Additional changes: - add a dso variable to avoid repeated map__dso calls. - in builtin-mem.c dump_raw_samples, code only partially tested for dso == NULL. Make the possibility of NULL consistent. - in thread.c thread__memcpy fix use of spaces and use tabs.

perf hists: Split hists_stats from events_stats
Each struct hists have events_stats but most of the fields were not used. It's to count number of samples and periods whether filtered or not. And other fields are used only by evlist.
So it'd be better to split hists_stats and events_stats to reduce wasted memory in the struct hists. This makes the output of event statistics in the perf report compact by skipping 0 events in each evsel/hists.

perf top/report: Fix infinite loop in the TUI for grouped events
For a while we need to have a dummy event for doing things like receiving PERF_RECORD_COMM, PERF_RECORD_EXEC, etc for threads being created and dying while we synthesize the pre-existing ones at tool start.
This 'dummy' event is needed for keeping track of thread lifetime events early in the session but are uninteresting otherwise, i.e. no need to have it in a initial events menu for the non-grouped case, i.e. for:
# perf top -e cycles,instructions
or even for plain:
# perf top
When 'cycles' and that 'dummy' event are in place.
The code to remove that 'dummy' event ended up creating an endless loop for the grouped case, i.e.:
# perf top -e '{cycles,instructions}'
Fix it.

perf report TUI: Fix segmentation fault in perf_evsel__hists_browse()
The segmentation fault can be reproduced as following steps:
1) Executing perf report in tui.
2) Typing '/xxxxx' to filter the symbol to get nothing matched.
3) Pressing enter with no entry selected.
Then it will report a segmentation fault.
It is caused by the lack of check of browser->he_selection when accessing it's member res_samples in perf_evsel__hists_browse().
These processes are meaningful for specified samples, so we can skip these when nothing is selected.

In d10ec006dcd7 ("perf hists browser: Allow passing an initial hotkey") the hist_entry__title() call was cut'n'pasted to a function where the 'title' variable is a pointer, not an array, so the sizeof(title) continues syntactically valid but ends up reducing the real size of the buffer where to format the first line in the screen to 8 bytes, which makes the formatting at the title at each refresh to produce just the string "Samples ", duh, fix it by passing the size of the buffer.

perf report/top TUI: Support hotkeys to let user select any event for sorting
When performing "perf report --group", it shows the event group information together. In previous patch, we have supported a new option "--group-sort-idx" to sort the output by the event at the index n in event group.
It would be nice if we can use a hotkey in browser to select a event to sort.
For example,

When user press hotkey '3' (event index, starting from 0), it indicates to sort output by the forth event in group.

v6: --- Jiri provided a good improvement to eliminate unneeded refresh. This improvement is added to v6.
v2: --- 1. Report warning at helpline when index is invalid. 2. Report warning at helpline when it's not group event. 3. Use "case '0' ... '9'" to refine the code 4. Split K_RELOAD implementation to another patch.
