perf report: Add report.children config option
Add report.children config option for setting default value of callchain accumulation. It affects the report output only if perf.data contains callchain info.
A user can write .perfconfig file like below to enable accumulation by default:
$ cat ~/.perfconfig [report] children = true
And it can be disabled through command line:
$ perf report --no-children
