Anton Khirnov 86417b759f lavfi: get rid of FF_INTERNAL_FIELDS
This hack is used to limit the visibility of some AVFilterLink fields to
only certain files. Replace it with the same pattern that is used e.g.
in lavf AVStream/FFStream and avoid exposing these internal fields in a
public header completely.
