+This is almost identical to the SHA-1 function sha1-make-buffer-filler, except for the order (big-endian vs little-endian) the octets are stored in.
The buffer-filler is a state-machine with four states. :done, :data, :length and :zeropad. The initial state is :data. When there is no more data, #x80 is returned and the new state is either :write-length (if current word is 13 and current byte is 3) else :zeropad. If we enter :write-length we write the length in the last two 32 bit words and enter :done. In state :zeropad we write zeros until we reach word 13 and byte 3 and then enter :write-length. When we reach the :done state, the next call will return nil."
