/* The system description clients send with their login request, exactly as the client reported it (old Windows calls:
   compatibility values, not necessarily the player's real hardware). Written by the auth server at each successful
   login: the account's newest row gets last_seen, logins + 1 and the new memory_stats text while everything else is the
   same; otherwise a new row starts. ip is empty while log_login_addresses is off. memory_total_kb is the physical memory
   read from memory_stats (0: not read). Rows not seen for log_client_sysinfo_days are deleted by the log pruning task. */
