This commit modifies the existing wire.Message interface to introduce a new MessageEncoding variant which dictates the exact encoding to be used when serializing and deserializing messages. Such an option is now necessary due to the segwit soft-fork package, as btcd will need to be able to optionally encode transactions/blocks without witness data to un-upgraded peers. Two new functions have been introduced: ReadMessageWithEncodingN and WriteMessageWithEncodingN which wrap BtcDecode/BtcEncode with the desired encoding format.
