Subject: [PATCH 2/8] perf annotate: Fix --show-total-period for tui/stdio2

perf annotate --show-total-period does not really show total period.
The reason is we have two separate variables for the same purpose.
One is in symbol_conf.show_total_period and another is
annotation_options.show_total_period. We save command line option
in symbol_conf.show_total_period but uses
annotation_option.show_total_period while rendering tui/stdio2 browser.

Though, we copy symbol_conf.show_total_period to
annotation__default_options.show_total_period but that is not really
effective as we don't use annotation__default_options once we copy
default options to dynamic variable annotate.opts in cmd_annotate().

Instead of all these complication, keep only one variable and use it
all over. symbol_conf.show_total_period is used by perf report/top as
well. So let's kill annotation_options.show_total_period.

On a side note, I've kept annotation_options.show_total_period definition
because it's still used by perf-config code. Follow up patch to fix
perf-config for annotate will remove annotation_options.show_total_period.
