Subject: [PATCH] Add the encoder/decoder getter methods to HttpClientCodec

Motivation:

There's no way for a user to get the encoder and the decoder of an
HttpClientCodec.  The lack of such getter methods makes it impossible to
remove the codec handlers from the pipeline correctly.

For example, a user could add more than one HttpClientCodec to the
pipeline, and then the user cannot easily decide which encoder and
decoder to remove.

Modifications:

- Add encoder() and decoder() method to HttpClientCodec which returns
  HttpRequestEncoder and HttpResponseDecoder respectively
- Also made the same changes to HttpServerCodec

Result:

A user can distinguish the handlers added by multiple HttpClientCodecs
easily.
