Subject: [PATCH v2 0/4] perf config: Introduce default config key-value pairs arrays

We currently use values of actual type(int, bool, char *, etc.)
when initializing default perf config values.

For example,
If there isn't user config value at ~/.perfconfig for 'annotate.use_offset' config variable,
default value for it is 'true' bool type value in perf like below.

At ui/browsers/annoate.c

static struct annotate_browser_opt {
       bool hide_src_code,
            use_offset,
	    jump_arrows,
	    show_linenr,
	    show_nr_jumps,
	    show_total_period;
} annotate_browser__opts = {
       .use_offset      = true,
       .jump_arrows     = true,
};

But I suggest using new config arrays that have all default config key-value pairs
and then initializing default config values with them.
Because if we do, we can manage default perf config values at one spot (like util/config.c)
and It can be easy and simple to modify default config values or add new configs.

For example,
If we use new default config arrays and there isn't user config value for 'annoate.use_offset'
default value for it will be set as annotate_config_items[CONFIG_ANNOATE_USE_OFFSET].value
instead of actual boolean type value 'true'.

IMHO, I think it should be needed to use new default config arrays
to manage default perf config values more effectively.
And this pathset contains patchs for only 'colors' and 'annoate' section
because waiting for other opinions.

If you review this patchset, I'd appreciate it :-)

Thanks,
Taeung

v2:
- rename 'ui_browser__config_gcolors' to 'ui_browser__config_colors' (Arnaldo)
- change 'ground colors' to '{back, fore}ground colors' (Arnaldo)
- use strtok + ltrim instead of strchr and while (isspace(*++bg)); (Arnaldo)

Taeung Song (4):
  perf config: Introduce default_config_item for all default config
    key-value pairs
  perf tools: Separate out code setting {back, fore}ground colors from
    ui_browser__color_config
  perf config: Initialize ui_browser__colorsets with default config
    items
  perf config: Initialize annotate_browser__opts with default config
    items
