Subject: [PATCH 10/10] perf tools: Remove some unused functions from color.c

From: Rickard Strandqvist <rickard_strandqvist@...ctrumdigital.se>

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.
