FreeBSD random number generator broken for last 4 months

As a reminder: with DSA, keys not only generated, but merely *used* on a system with a broken RNG are compromised. (This does not apply to deterministic DSA or EdDSA.)

So if for instance the system had a ssh ECDSA key generated with a non-broken RNG, but used with a broken RNG, it should be discarded and regenerated (unless openssh used deterministic ECDSA).
