This contains two implementation: a machine-generated formally verified
implementation of Curve25519 ECDH from:
<https://github.com/mit-plv/fiat-crypto>. Though originally machine
generated, it has been tweaked to be suitable for use in the kernel. It is
optimized for 32-bit machines and machines that cannot work efficiently with
128-bit integer types.
