Marek Kotewicz 044d070667 rlp deserialization refactor, 30% faster (#4901)
* 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
