    Don't send uninitialized data in command replies
    
    The RPY_SUBNETS_ACCESSED and RPY_CLIENT_ACCESSES command replies can
    contain uninitalized data from stack when the client logging is disabled
    or a bad subnet is requested. These commands were never used by chronyc
    and they require the client to be authenticated since version 1.25.
