ffi: arrays: be more forgiving of length mismatches.
* ffi.c (min): New macro.
(ffi_array_put_common): Tolerate sequences which are shorter
than the array. Use seq_info to classify the sequence and use
separate code for the vector and list case, avoiding taking
the length of the list.
* txr.1: Documented.
