    kernel - add a fortuna-based CSPRNG
    
     * This implements a Fortuna-based CSPRNG.
    
     * All entropy pools are shared across all CPUs in the system.
    
     * SHA256 is used instead of SHA256_d as cryptographical hash
       function.
    
     * ChaCha is used as stream cipher instead of AES in CTR mode.
