Devrandom 4826d0c6cc no_std support 
Based on the original work by Justin Moon.

*MSRV unchanged from 1.29.0.*

When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.

* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so

Alekos Filini 373f355b5a Flush unrecognized network messages from the read buffer 
Currently whenever an unrecognized network message is received, it is never
flushed from the read buffer, meaning that unless the stream is closed and
recreated it will keep returning the same error every time `read_next()` is
called.

This commit adds the length of the message to `UnrecognizedNetworkCommand`,
so that the `StreamReader` can flush those bytes before returning the error
to the caller.

Dr. Maxim Orlovsky 3c21e301aa Better RawNewtorkMessage deserealization from IO stream (#231) 
Follow-up to https://github.com/rust-bitcoin/rust-bitcoin/pull/229

While working with remote peers over the network it is required to deserealize RawNetworkMessage from `TCPStream` to read the incoming messages. These messages can be partial – or one TCP packet can contain few of them. To make the library usable for such use cases, I have implemented the required functionality and covered it with unit tests.

Sample usage:
```rust
fn run() -> Result<(), Error> {
    // Opening stream to the remote bitcoind peer
    let mut stream = TcpStream::connect(SocketAddr::from(([37, 187, 0, 47], 8333));
    let start = SystemTime::now();

    // Constructing and sending `version` message to get some messages back from the remote peer
    let since_the_epoch = start.duration_since(UNIX_EPOCH)
        .expect("Time went backwards");
    let version_msg = message::RawNetworkMessage {
        magic: constants::Network::Bitcoin.magic(),
        payload: message::NetworkMessage::Version(message_network::VersionMessage::new(
            0,
            since_the_epoch.as_secs() as i64,
            address::Address::new(receiver, 0),
            address::Address::new(receiver, 0),
            0,
            String::from("macx0r"),
            0
        ))
    };
    stream.write(encode::serialize(&version_msg).as_slice())?;

    // Receiving incoming messages
    let mut buffer = vec![];
    loop {
        let result = StreamReader::new(&mut stream, None).read_messages();
        if let Err(err) = result {
            stream.shutdown(Shutdown::Both)?;
            return Err(Error::DataError(err))
        }
        for msg in result.unwrap() {
            println!("Received message: {:?}", msg.payload);
        }
    }
}
```

Sample output is the following:
```
Received message: Version(VersionMessage { version: 70015, services: 1037, timestamp: 1548637162, receiver: Address {services: 0, address: [0, 0, 0, 0, 0, 65535, 23536, 35968], port: 33716}, sender: Address {services: 1037, address: [0, 0, 0, 0, 0, 0, 0, 0], port: 0}, nonce: 1370726880972892633, user_agent: "/Satoshi:0.17.99/", start_height: 560412, relay: true })
