Right to access and right to data portability

[eliasgruenewald]

So far, we have:

• Access and data portability (both - was intended for Art. 15(2) and Art. 46, respectively; but actually I don't think it really happens in practice. It is simply covered in the third country transfers).

• Right to data portability (means Art. 20 scenario)

• Right to information (means Art. 15 scenario; should better be called right to access)

We can possibly deduplicate this.
