Subject[PATCH 15/21] perf report: Add report.children config option
Date
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
