mononoke: update internals to Bytes 0.5
Summary:
The Bytes 0.5 update left us in a somewhat undesirable position where every
access to our blobstore incurs an extra copy whenever we fetch data out of our
cache (by turning it from Bytes 0.5 into Bytes 0.4) — we also have quite a few
place where we convert in one direction then immediately into the other.
Internally, we can start using Bytes 0.5 now. For example, this is useful when
pulling data out of our blobstore and deserializing as Thrift (or conversely,
when serializing and putting it into our blobstore).
However, when we interface with Tokio (i.e. decoders & encoders), we still have
to use Bytes 0.4. So, when needed, we convert our Bytes 0.5 to 0.4 there.
The tradeoff idea is that we deal with more bytes internally than we end up
sending to clients, so doing the Bytes conversion closer to the point of
sending data to clients means less copies.
We can also start removing those once we migrate to Tokio 0.2 (and newer
versions of Hyper for HTTP services).
Changes that were required:
- You can't extend new bytes (because that implicitly copies). You need to use
BytesMut instead, which I did where that was necessary (I also added calls in
the Filestore to do that efficiently).
- You can't create bytes from a `&'a [u8]`, unless `'a` is `'static`. You need
to use `copy_from_slice` instead.
- `slice_to` and `slice_from` have been replaced by a `slice()` function that
takes ranges.
