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 ca72a04dd4 Remove rust-crypto dependency 
We no longer need rust-crypto after integrating bitcoin_hashes.
 2019-01-24 16:27:52 -05:00
Carl Dong b88f00c698 Add bitcoin_hashes dependency, rename some features 
Because features and dependencies share the same namespace, and we want
to pass down the optional dependence on serde to bitcoin_hashes, we need
to rename the feature to something other than serde. Right now only
features can be passed down to dependencies.

Note that we could have also renamed the dependency to something like
serde-dep and kept the same feature name, however, dependency renaming
has only been available since cargo 0.27.0

Features that represent optional dependencies have been prefixed with
'use-'. The travis file has also been modified to conform to this
change.

Jean Pierre Dudey 1b4aba1d80 Update serde to 1.0 and strason to 0.4 
The `serde_struct_impl!` macro has been modified to be compatible
with the serde 1.0 crate, we use this macro and not the `serde_derive`
crate because the latter doesn't support Rust 1.14.0 which is shipped
on Debian stable and we should remain compatible with it.

Two new features were added:

- "serde": enables serialization/deserialization for common types, it pulls
the serde 1.0 dependency.
- "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`,
this pulls the strason 0.4 depdendency and the serde 1.0 dependency.

Savil Srivastava 933dcaeb82 [code hygiene] remove deprecated rustc-serialize 
Addresses #96.

Turns out it was being used for hex encoding/decoding, so replaced that with the `hex` crate.

i chose to import the `decode` method as:
```
use hex::decode as hex_decode
```

so that it is clear to the reader what is being decoded when it is called. "decode" is such a generic sounding function name that it would get confusing otherwise.
