At this point, the only special behavior of bridge_fn_buffer is to support multiple return values for the C bridge (a pointer/length pair), and that doesn't pull its weight. Remove it in favor of a plain bridge_fn. This did reveal that Username_Hash was using bridge_fn_buffer and now produces a fixed-size array, imported into Swift as a tuple, so this commit also factors out a new helper invokeFnReturningFixedLengthArray.
