@newpavlov since this is still blocked by a new chacha20 release can you also review #1727? I'll rebase this after.

Updated.

I could put out a new rand RC with this, but I won't bother without a good reason. The chacha20 RC.11 did not bring breaking changes so the current rand RC should still be fine using that.

@dhardy I can put out another RC with RustCrypto/stream-ciphers#529 though hopefully it didn't impact anything in rand?
