Subject: string-output-visitor: Favor new visit_free() function
X-Git-Tag: TizenStudio_2.0_p4.0~6^2~12^2~6^2~138^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e7ca56562990991bc614a43b9351ee0737f3045d;p=sdk%2Femulator%2Fqemu.git

string-output-visitor: Favor new visit_free() function

Now that we have a polymorphic visit_free(), we no longer need
string_output_visitor_cleanup(); however, we still need to
expose the subtype for string_output_get_string().
