Jonas Ådahl 4a4f2d8264 output: Make implementations inherit MetaOutput 
Instead of the home baked "inheritance" system, using a gpointer and a
GDestroyNotify function to keep the what effectively is sub type
details, make MetaOutput an abstract derivable type, and make the
implementations inherit it.
