Subject[PATCH 20/21] perf top: Add top.children config option
Date
Add top.children config option for setting default value of
callchain accumulation. It affects the output only if one of
-g or --call-graph option is given as well.

A user can write .perfconfig file like below to enable accumulation
by default:

$ cat ~/.perfconfig
[top]
children = true

And it can be disabled through command line:

$ perf top --no-children
