[PATCH v3 5/7] perf config: Reimplement show_config() using perf_config()

From: Taeung Song
Date: Mon May 30 2016 - 12:44:40 EST


Old show_config() directly use config set so
there are many duplicated code with perf_config_set__iter().

So reimplement show_config() using perf_config() that use
perf_config_set__iter() with config set that already
contains all configs.
