Encoders and decoders for HTTP/1.x messages based on [bytecodec] crate.

[Documentation](https://docs.rs/httpcodec)

[bytecodec]: https://crates.io/crates/bytecodec

Examples
--------

Encodes a HTTP request message:

```rust
use bytecodec::Encode;
use bytecodec::bytes::BytesEncoder;
use bytecodec::io::IoEncodeExt;
use httpcodec::{BodyEncoder, HttpVersion, Method, Request, RequestEncoder, RequestTarget};

let request = Request::new(
    Method::new("GET").unwrap(),
    RequestTarget::new("/foo").unwrap(),
    HttpVersion::V1_1,
    b"barbaz",
);

let mut encoder = RequestEncoder::new(BodyEncoder::new(BytesEncoder::new()));
encoder.start_encoding(request).unwrap();

let mut buf = Vec::new();
encoder.encode_all(&mut buf).unwrap();
assert_eq!(buf, "GET /foo HTTP/1.1\r\ncontent-length: 6\r\n\r\nbarbaz".as_bytes());
```

Decodes a HTTP response message:

```rust
use bytecodec::bytes::RemainingBytesDecoder;
use bytecodec::io::IoDecodeExt;
use httpcodec::{BodyDecoder, HttpVersion, ResponseDecoder};

let mut decoder =
    ResponseDecoder::<BodyDecoder<RemainingBytesDecoder>>::default();

let input = b"HTTP/1.0 200 OK\r\ncontent-length: 6\r\n\r\nbarbaz";
let response = decoder.decode_exact(input.as_ref()).unwrap();

assert_eq!(response.http_version(), HttpVersion::V1_0);
assert_eq!(response.status_code().as_u16(), 200);
assert_eq!(response.reason_phrase().as_str(), "OK");
assert_eq!(
    response.header()
        .fields()
        .map(|f| (f.name().to_owned(), f.value().to_owned()))
        .collect::<Vec<_>>(),
    vec![("content-length".to_owned(), "6".to_owned())]
);
assert_eq!(response.body(), b"barbaz");
```
