Details

The certificates used by Abridged Certificates are loaded via RemoteSettings. We need to efficiently check whether these certificates are available when advertising support for a particular dictionary.

We can alter the check for present certificates to use a cache with a key provided by the caller. This cache will immediately return whether the certificates are available. Negative answers in the cache (there are missing certificates) will be expired whenever new certificates are added. Positive answers in the cache (the certificates are present) will be expired whenever existing certificates are removed.
