[PATCH v6 3/7] perf config: Add a option 'list-all' to perf-config

From: Taeung Song
Date: Wed Sep 23 2015 - 02:57:34 EST

A option 'list-all' is to display both current config variables and
all possible config variables with default values.
The syntax examples are like below

perf config [<file-option>] [options]

display all perf config with default values.
# perf config -a | --list-all
