We have very featureful color-parsing routines which are used for color.diff.* and other options. Let's make it easier to use those routines from other parts of the code. This patch adds a color_parse_mem() helper function which takes a length-bounded string instead of a NUL-terminated one. While the helper is only a few lines long, it is nice to abstract this out so that: - callers don't forget to free() the temporary buffer - right now, it is implemented in terms of color_parse(). But it would be more efficient to reverse this and implement color_parse in terms of color_parse_mem. This also changes the error string for an invalid color not to mention the word "config", since it is not always appropriate (and when it is, the context is obvious since the offending config variable is given). Finally, while we are in the area, we clean up the parameter names in the declaration of color_parse; the var and value parameters were reversed from the actual implementation.
