[PATCH 0/6] perf config: Add support for setting and getting functionalities

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

Hello, :)

Add setting and getting features to perf-config.

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/2016/10/24/47.

In particular, I agonized implement way for setting functionality.
I especially wonder other opinions of new perf_config_set__collect()
and bool from_system_config variable.

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

Thanks,
Taeung
