add strbuf_expand_dict_cb(), a helper for simple cases
The new callback function strbuf_expand_dict_cb() can be used together with strbuf_expand() if there is only a small number of placeholders for static replacement texts. It expects its dictionary as an array of placeholder+value pairs as context parameter, terminated by an entry with the placeholder member set to NULL. The new helper is intended to aid converting the remaining calls of interpolate(). strbuf_expand() is smaller, more flexible and can be used to go faster than interpolate(), so it should replace the latter.
