* fixed naming of rlp modules * RlpStream cleanup * appending short rlp lists (0...55 bytes) is 25% faster * RlpStream does not use bytes module, nor trait Stream * removed unused code from rlp module * compiling ethcore-util with new rlp serialization * compiling parity with new rlp serialization * fixed compiling ethcore-light with new rlp serialization * fixed compiling ethsync with new rlp serialization * removed redundant comment, print * removed redundant double-space * replace usage of WriteBytesExt with ByteOrder
