Cast device certificates may be revoked through two ways:
1. The hash of the public key.
2. A serial number range for an issuer identified by the hash
   of its public key.

A customized proto is used as the medium for this information.

This change contains the implementation for verifying the custom CRL
and verifying a certificate's revocation status based on that CRL.
