Eliza Weisman 647299866a util: add writev-aware poll_write_buf (#3156) 
## Motivation

In Tokio 0.2, `AsyncRead` and `AsyncWrite` had `poll_write_buf` and
`poll_read_buf` methods for reading and writing to implementers of
`bytes` `Buf` and `BufMut` traits. In 0.3, these were removed, but
`poll_read_buf` was added as a free function in `tokio-util`. However,
there is currently no `poll_write_buf`.

Now that `AsyncWrite` has regained support for vectored writes in #3149,
there's a lot of potential benefit in having a `poll_write_buf` that
uses vectored writes when supported and non-vectored writes when not
supported, so that users don't have to reimplement this.

## Solution

This PR adds a `poll_write_buf` function to `tokio_util::io`, analogous
to the existing `poll_read_buf` function.

This function writes from a `Buf` to an `AsyncWrite`, advancing the
`Buf`'s internal cursor. In addition, when the `AsyncWrite` supports
vectored writes (i.e. its `is_write_vectored` method returns `true`),
it will use vectored IO.

I copied the documentation for this functions from the docs from Tokio
0.2's `AsyncWrite::poll_write_buf` , with some minor modifications as
appropriate.

Finally, I fixed a minor issue in the existing docs for `poll_read_buf`
and `read_buf`, and updated `tokio_util::codec` to use `poll_write_buf`.

Carl Lerche d78655337a Revert "util: upgrade tokio-util to bytes 0.6 (#3052)" (#3060) 
This reverts commit fe2b997.

We are avoiding adding poll_read_buf to tokio itself for now. The patch is
reverted now in order to not block the v0.3.2 release (#3059).
