Update auto-generated code

This patch updates the auto-generated code to match the latest tooling
versions.

In particular, the protobufs are regenerated, and the new version no
longer supports unkeyed literals, so some minor changes are needed.

Other than that, the cipher list is extended with the latest ciphers.
