Subject: [PATCH 1/8] perf annotate: Introduce global annotation_options
The annotation options are to control the behavior of objdump and the
output. It's basically used by perf annotate but perf report and perf
top can call it on TUI dynamically. But it doesn't need to have a copy
of annotation options in many places. As most of the work is done in
the util/annotate.c file, add a global variable and set/use it instead
of having their own copies.
