This leaves only aborting stubs (for SONAME stability) for

  typelib_static_array_type_init
  typelib_typedescription_newArray
  typelib_typedescription_newUnion

and completely removes corresponding

  typelib_ArrayTypeDescription
  typelib_UnionTypeDescription

structs and C++ inline

  getCppuArrayType*

functions.  None of this should ever have been called by client code anyway, so
while technically an API change it should not matter for practical purposes.
