To make the output more readable, I think it's better to remove 0's in
the output. Also the dummy event has no event stats so it just wasts
the space. Let's use the --skip-empty option to suppress it.
$ perf report --stat --skip-empty
Aggregated stats:
TOTAL events: 16530
MMAP events: 226
COMM events: 1596
EXIT events: 2
THROTTLE events: 121
UNTHROTTLE events: 117
FORK events: 1595
SAMPLE events: 719
MMAP2 events: 12147
CGROUP events: 2
FINISHED_ROUND events: 2
THREAD_MAP events: 1
CPU_MAP events: 1
TIME_CONV events: 1
cycles stats:
SAMPLE events: 719

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.

Fix ~124 single-word typos and a few spelling errors in the perf tooling code,
accumulated over the years.

This will allow us to untangle the header dependency a bit more, as some
places will not need event.h anymore.
