Cleanup: unconstify string argument to add_to_string()

Browse source 
add_to_string() frees the original string that is passed in. This
should therefore not be of "const char *" type, as the contents
of the string *will* be modified (or more precisely: destroyed).

Same for the congener smtk_concat_str().
