      Bug#14197426 parse errors in loadable UCA / LDML collations are silently ignored
           
      Problem: character set and collation errors in a running mysqld
      were erroneously sent to buffered_log, which is intended to
      be used only at earlier mysqld initialization step and should not
      be used after initialization.
      
      Fix: send character set and collation errors in a initialized
      server directly to error log instead of buffered_logs.

      Patch for WL#6301 (Change default value for the 'bind-address' option).
      
      The patch consists of two parts:
      
        - the patch introduces a new special value for the bind-address
          option: * (a star). This value means, the server should listen to
          all network addresses, both IPv6 (if available) and IPv4.
      
        - the patch changes the bind-address default value to star (*).
