strbuf: add strbuf_tolower function
This is a convenience wrapper to call tolower on each character of the string. This makes config's lowercase() function obsolete, though note that because we have a strbuf, we are careful to operate over the whole strbuf, rather than assuming that a NUL is the end-of-string. We could continue to offer a pure-string lowercase, but there would be no callers (in most pure-string cases, we actually duplicate and lowercase the duplicate, for which we have the xstrdup_tolower wrapper).
