[PATCH] tools: perf: util: color.c: Remove some unused functions

[PATCH] tools: perf: util: color.c: Remove some unused functions

[Rickard Strandqvist]

Removes some functions that are not used anywhere:
color_parse_mem() color_parse()

This was partially found by using a static code analysis program called cppcheck.

Removed the now unused parse_{attr,color} static routines and I'm
running 'make -C tools/perf build-test' again to see if all goes well.

Humm, there is support for changing the TUI colors in ~/.perfconfig, but
probably it doesn't uses those functions?

void ui_browser__init(void)
{
        int i = 0;

        perf_config(ui_browser__color_config, NULL);

        while (ui_browser__colorsets[i].name) {
                struct ui_browser_colorset *c = &ui_browser__colorsets[i++];
                sltt_set_color(c->colorset, c->name, c->fg, c->bg);
        }

        annotate_browser__init();
}

And ui_browser__color_config does really simple parsing, using straight
away the color strings provided in the config file.

Looking again, we could even use those, after adapting it to what
libslang expects, not what ncurses do, but I haven't checked, perhaps
libslang will do that validation for us, in the meantime, I'm applying
the patch.

perf tools: Remove some unused functions from color.c

Removes some functions that are not used anywhere:

 color_parse_mem()
 color_parse()

This was partially found by using a static code analysis program called cppcheck.
