Libindy 1.12 to 1.13 migration

Anoncreds API

We have introduced some new functionality in revealed attributes -- you can specify multiple attributes in a single revealed attribute unit using parameter names. That way you will receive revealed attributes from a single credential. API calls that have changed:

• indy_prover_get_credentials_for_proof_req
• indy_prover_search_credentials_for_proof_req
• indy_prover_create_proof

Last call have a new attribute in a response -- revealed_attr_groups -- it contains data about revealed attribute units with names field. Also, indy_verifier_verify_proof accepts this attribute in a requested_proof field.

Backwards compatibility

If Verifier (old) sends a proof request without names attribute to Prover (new) and it will receive proof without new fields.

If Verifier (new) sends a proof request with names attribute to Prover (old) it will not validate proof request because it will not have parameter name in it.
