(** Type checking for some inductive entry.
    Returns:
    - environment with inductives + parameters in rel context
    - abstracted universes
    - checked variance info
    - record entry (checked to be OK)
    - parameters
    - for each inductive,
      (arity * constructors) (with params)
      * (indices * splayed constructor types) (both without params)
      * top allowed elimination
