curve: add X25519_LOW_ORDER_POINTS constant (#814)
Adds a table of low order points, adapted from
https://cr.yp.to/ecdh.html, which suggests that non-Diffie-Hellman
protocols that depend on "contributory" behavior should reject them.

They're also useful for testing, e.g. how a protocol implementation
handles them during a key exchange (noting that a well-implemented AKE
shouldn't need to explicitly reject them, as someone attempting to use
them for MitM should be spotted as a transcript mismatch).

Dalek elliptic curve cryptography

This repo contains pure-Rust crates for elliptic curve cryptography:

Crate Description Crates.io Docs CI
curve25519dalek A library for arithmetic over the Curve25519 and Ristretto elliptic curves and their associated scalars. CI
ed25519dalek An implementation of the EdDSA digital signature scheme over Curve25519. CI
x25519dalek An implementation of elliptic curve Diffie-Hellman key exchange over Curve25519. CI

There is also the curve25519-dalek-derive crate, which is just a helper crate with some macros that make curve25519-dalek easier to write.
