From 56d9117c5004e7192d8062da67fef220e4fdcd19 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>

Subject: perf annotate: Own objdump_path and disassembler_style strings

Make struct annotation_options own the strings objdump_path and
disassembler_style, freeing them on exit. Add missing strdup for
disassembler_style when read from a config file.

Committer notes:

Converted free(obj->member) to zfree(&obj->member) in
annotation_options__exit()
