Verify ed25519 link handshake certificates

This code stores the ed certs as appropriate, and tries to check
them. The Ed25519 result is not yet used, and (because of its
behavior) this will break RSA authenticate cells.  That will get
fixed as we go, however.

This should implement 19157, but it needs tests, and it needs
to get wired in.
