[PATCH v2 0/7] perf config: Add support for config read/write

[Taeung Song <treeze.taeung@gmail.com>]

Hello, :)

Add simple config read/write functionalities.

I had worked at the related patchset https://lkml.org/lkml/2016/2/22/38 
But I remake new this patchset for only support for read/write config file.
And There're Namhyung's requests https://lkml.org/lkml/2016/10/24/572

In particular, I agonized implement way for write functionality.
I especially wonder other opinions about new boolean variable
'from_system_config' I use.

If someone review this patchset and give me some feedback,
I'd appreciated it. :)

Thanks,
Taeung
