 * List of hashes

 * Each hash must be wrapped in a thin redirector conformant with the BMK_benchfn_t.
 * BMK_benchfn_t is generic, not specifically designed for hashes.
 * For hashes, the following parameters are expected to be useless:
 * dst, dstCapacity, customPayload.
 *
 * The result of each hash is assumed to be provided as function return value.
 * This condition is important for latency measurements.
