Subject: [PATCH v3 5/7] perf config: Introduce perf_default_config_init()

default_*_config_init() initialize actual variables
with each default config value.
(e.g. default_colors_config_init() for 'colors' section)

But I suggest using perf_default_config_init() that call
all default_*_config_init() and this function would be called
at the very beginning of main() on perf.c.

In order to set all default config values before running
a particular sub-command. And if we do, we can manage
all default_*_config_init() functions in perf_default_config_init().
