Disposing resources acquired by `MessageEncoder` and `MessageDecoder`

Make your MessageEncoder and MessageDecoder to put all resources that need to be released as a session attribute. disposeCodecResources(IoSession) method will be invoked when a session is closed. Override disposeCodecResources(IoSession) to release the resources you've put as an attribute.

We didn't provide any dispose method for MessageEncoder and MessageDecoder because they can give you a big performance penalty in case you have a lot of message types to handle.
