perf annotate: Fix --show-total-period and support --show-nr-samples

Hello,

Currently the --show-total-period option of perf-annotate is different from perf-report's.

It has two problem like below:
(Reported by Namhyung Kim and Milian Wolff)

1) Wrong column i.e. 'Percent' (even though using --show-total-period)
2) Show number of samples, not period

So fix this option on both the annotate stdio and TUI browser. And support --show-nr-samples into perf-anntate
so that it correpond with perf-report's.

The code is available on 'perf/ann-fix-period-v2' branch at

git://github.com/taeung/linux-perf.git

Thanks,
Taeung

v2:
- Separate the first patch into respective paches for easy review (Arnaldo)
- Add a patch to introduce 'struct sym_hist_entry' (Arnaldo)
- disasm__calc_percent() could receive a pointer to a struct sym_hist_entry instead of two pointer (Arnaldo)
- Add a sym_hist_entry into struct disasm_line_samples (Arnaldo)
- Fix a case that can't switch 'the total period view' to
'the number of samples view' on the annotate TUI browser (Arnaldo)
- Calculate the percentage with 'period', not number of samples

perf annotate: Introduce struct sym_hist_entry

It seems I didn't receive the patch 3 and 5 for some reason. Anyway I have a few comments.
