Gwenole Beauchesne d45c6a486f encoder: clean-up objects.
Various clean-ups to improve consistency and readability: rename some
variables, drop unused macro definitions, drop initialization of vars
that are zero-initialized from the base class, drop un-necessary casts,
allocate GPtrArrays with a destroy function.
