EVP_MD_size() updates

For SHAKE algorithms we now return 0 from EVP_MD_size().
So all the places that check for < 0 needed to change to <= 0
(Otherwise the behaviour will be to digest nothing in most cases).

Explicitly initialize the peer_rpk variable to make the compiler happy.

Yes, it's a false positive, but you have to check the tls_process_rpk()
body in another source file to see that, which apparently is beyond the
compiler's capabilities.

Change the TLS handshake keys early if we're not doing early data

We change the client TLS handshake keys as late as possible so that we
don't disturb the keys if we are writing early data. However for QUIC we
want to do this as early as possible (after ServerHello). Since we will
never do TLS early data with QUIC we just do it as early as possible if
early data is not being used.
