This commit is a significant overhaul of the library in an effort to head towards a stable API. The rope implementation as well as a number of buffer implementations have been removed from the library and will live at https://github.com/carllerche/bytes-more while they incubate. **Bytes / BytesMut** `Bytes` is now an atomic ref counted byte slice. As it is contigous, it offers a richer API than before. `BytesMut` is a mutable variant. It is safe by ensuring that it is the only handle to a given byte slice. **AppendBuf -> ByteBuf** `AppendBuf` has been replaced by `ByteBuf`. The API is not identical, but is close enough to be considered a suitable replacement. **Removed types** The following types have been removed in favor of living in bytes-more * RingBuf * BlockBuf * `Bytes` as a rope implementation * ReadExt * WriteExt
