/*! \brief CERTFP command handler (called by remotely connected clients)
 *
 * \param client_p Pointer to allocated Client struct with physical connection
 *                 to this server, i.e. with an open socket connected.
 * \param source_p Pointer to allocated Client struct from which the message
 *                 originally comes from.  This can be a local or remote client.
 * \param parc     Integer holding the number of supplied arguments.
 * \param parv     Argument vector where parv[0] .. parv[parc-1] are non-NULL
 *                 pointers.
 * \note Valid arguments for this command are:
 *      - parv[0] = sender prefix
 *      - parv[1] = certificate fingerprint
