    Description

      When connecting to MariaDB Server running with OpenSSL 1.1.1 TLSv1.3 connection will fail with error 

      Lost connection to MySQL server at 'reading authorization packet', system error: 11

      The TLS handshake itself succeeds but further reads will fail:

      Solution: check the return code of gnutls_record_recv/send and repeat if return code was GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPT.

          Fix for CONC-423: GnuTLS fails with "error reading authentication packet" with a TLSv1.3 connection

          We now check the return code of gnutls_record_send() and gnutls_record_recv().
          If GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED was returned we will loop and read/write
          again until a timeout occurs or buffer was read or written.
