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 })

```

Carl Dong a944c7fbd0 key: Use correct error for decoding 
This change also moves the secp256k1::Error wrapper from util::Error to
consensus::encode::Error, since we do not use it anywhere else. We can
add it back to util::Error once we have instances of secp256k1::Error
that are not related to consensus::encode.
