The encoder is a true gstobject now and all the properties are using gobject's properties mechanism. Add help functions to handle the properties between encode and encoder class. The basic idea is mapping the same property between encoder and encode. All the encoder's properties will have the same name, the same type in encode. The set/get property function just forward the property setting/getting to the encoder using the same property name and value. Because the encoder is created on needed, we need to cache the property setting in encode.
