* 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 * moved rlp benches and rlp tests * rlp deserialization refactor, 30% faster * removed redundant comment, print * fixed compiling parity with new rlp deserialization * removed redundant double-space * fixed failing test * updated rlp docs, removed unused traits * fixed rlp benchmarks * replace usage of WriteBytesExt with ByteOrder * removed unused, commented out code * fixed merge conflict
