Retrofit the codec framework with the new API (in progress) 

- Replaced FrameDecoder and OneToOne(Encoder|Decoder) with:
  - (Stream|Message)To(String|Message)(Encoder|Decoder)
- Moved the classes in 'codec.frame' up to 'codec'
- Fixed some bugs found while running unit tests

* Decodes the received {@link ChannelBuffer}s into a meaningful frame object.
* <p>
* In a stream-based transport such as TCP/IP, packets can be fragmented and
* reassembled during transmission even in a LAN environment. For example,
* let us assume you have received three packets:
* <pre>
* +-----+-----+-----+
* | ABC | DEF | GHI |
* +-----+-----+-----+
* </pre>
* because of the packet fragmentation, a server can receive them like the
* following:
* <pre>
* +----+-------+---+---+
* | AB | CDEFG | H | I |
* +----+-------+---+---+
* </pre>
* <p>
* {@link FrameDecoder} helps you defrag the received packets into one or more
* meaningful <strong>frames</strong> that could be easily understood by the
* application logic. In case of the example above, your {@link FrameDecoder}
* implementation could defrag the received packets like the following:
* <pre>
* +-----+-----+-----+
* | ABC | DEF | GHI |
* +-----+-----+-----+
* </pre>
* <p>
* The following code shows an example handler which decodes a frame whose
* first 4 bytes header represents the length of the frame, excluding the
* header.
* <pre>
* MESSAGE FORMAT
* ==============
*
* Offset: 0 4 (Length + 4)

*
* <h3>Returning a POJO rather than a {@link ChannelBuffer}</h3>
* <p>
* Please note that you can return an object of a different type than
* {@link ChannelBuffer} in your {@code decode()} and {@code decodeLast()}
* implementation. For example, you could return a
* <a href="http://en.wikipedia.org/wiki/POJO">POJO</a> so that the next
* {@link ChannelUpstreamHandler} receives a {@link MessageEvent} which
* contains a POJO rather than a {@link ChannelBuffer}.
*
* <h3>Replacing a decoder with another decoder in a pipeline</h3>
* <p>
* If you are going to write a protocol multiplexer, you will probably want to
* replace a {@link FrameDecoder} (protocol detector) with another
* {@link FrameDecoder} or {@link ReplayingDecoder} (actual protocol decoder).
* It is not possible to achieve this simply by calling
* {@link ChannelPipeline#replace(ChannelHandler, String, ChannelHandler)}, but
* some additional steps are required:
* <pre>
* public class FirstDecoder extends {@link FrameDecoder} {
*
* public FirstDecoder() {
* super(true); // Enable unfold
* }
*
* {@code @Override}
* protected Object decode({@link ChannelHandlerContext} ctx,
* {@link Channel} channel,
* {@link ChannelBuffer} buf) {
* ...
* // Decode the first message
* Object firstMessage = ...;
*
* // Add the second decoder
* ctx.getPipeline().addLast("second", new SecondDecoder());
*
* // Remove the first decoder (me)
* ctx.getPipeline().remove(this);
*
* if (buf.readable()) {
* // Hand off the remaining data to the second decoder
* return new Object[] { firstMessage, buf.readBytes(buf.readableBytes()) };
* } else {
* // Nothing to hand off
* return firstMessage;
* }
* }
* }
