[PATCH v8 3/4] perf config: Prepare all default configs

From: Taeung Song
Date: Thu Apr 14 2016 - 03:54:27 EST

To precisely manage configs,
prepare all default perf's configs that contain
default section name, variable name, value
and correct type, not string type.

In the near future, this will be used when
checking type of config variable or showing
all configs with default values, etc.
