------------------------------------+------------------------------------
 The `ref10` Ed25519 code currently being used is rather slow, and does not
 support batch verification.  Andrew Moon's `Ed25519-donna`
 (https://github.com/floodyberry/ed25519-donna) is both faster and provides
 batch verification, in addition to the optimized Curve25519 scalar
 basepoint multiply that #9663 depends on.

 We should use Ed25519-donna instead of ref10 for our Ed25519
 implementation, at first with cross-checking/fallback, and eventually as
 our sole Ed25519 provider.
