- Split 'verify_fcurve' into two functions: ED_action_fcurve_ensure which adds the f-curve if needed. ED_action_fcurve_find which returns NULL when not found. Callers of ED_action_fcurve_find had unused 'group' argument which has been removed. - Rename verify_adt_action to ED_id_action_ensure It had an argument to add data which was always true, remove this instead of splitting in into a separate function.
