x448 - curve448 ECDH
Yawning Angel (yawning at schwanenlied dot me)
A straight forward port of Michael Hamburg's x448 code to Go lang.
See: https://www.rfc-editor.org/rfc/rfc7748.txt
If you're familiar with how to use golang.org/x/crypto/curve25519, you will be right at home with using x448, since the functions are the same. Generate a random secret key, ScalarBaseMult() to get the public key, etc etc etc.
Both routines return 0 on success, -1 on failure which MUST be checked, and the handshake aborted on failure.
