[Tarantool-patches] [PATCH] lua: show error on attempt to access to tuple of unsupported type

[Vladislav Shpilevoy]

Hi!

I dove into the issue context, and from what I see, this
commit does not fix anything.

The issue is much deeper that just msgpackffi decoder problem.
Moreover, you said it is 'fixed' for 1.10, but the problem
exists not only on 1.10. It is a general problem of any version
interacting with any newer version.

Besides, I see Alexander Tu. provided lots of comments, which
you didn't address. So please, proceed with fixing his comments
first.

In my opinion, we should hide spaces with unknown fields. I.e.
whose tuple_format object couldn't be created on the client side.
It looks like the simplest option. The client anyway can't do
anything useful with these spaces.
