Elliptic curve Qu-Vanstone implicit certificate scheme (ECQV) for Ristretto

Implicit certificates provide an extremely space efficent public key certificate scheme.

As a rule, implicit certificates do not prove possession of the private key. We thus worry more about fear rogue key attack when using them, but all protocols here should provide strong defenses against then.
