Thank you for the update. Feature wise, this looks fine to me, though I would like to see a unit test covering this function - maybe you could modify tests/handshake-write.c to update keys on both server and client, and ensure they can still transfer data with each other.

It's also tempting to remove "trigger" from the function name, as it doesn't trigger but just updates the receiving key. Maybe `gnutls_handshake_update_receiving_key`?
