      Provide an replication API for the binary log interface:

      MARIADB_RPL *mariadb_rpl_init(void);
      		 
      int mariadb_rpl_optionv(MARIADB_RPL *, enum rpl_option, ...);
      		 
      int mariadb_rpl_open(MYSQL *, MARIADB_RPL *);
      		 
      void mariadb_rpl_close(MARIADB_RPL *);
      		 
      int mariadb_rpl_fetch(MYSQL *, MARIADB_RPL *);
      		 
      void mariadb_free_rpl_event(MARIADB_RPL_EVENT *event);

            There is nor mariadb_rpl.c in sources cloned from git. Please, add it to repo.

            Had a look on feature...

            I there any further work going on it this?

            Some things about current status...

            • Fixed header lengths are not taken from Description event and
              event parsing is not divided between fixed+variables parts.
              This would enable some compatibility between versions (I think).
            • QUERY event status variable block is not parsed.
              This could be separate parsing (from binary log) from event structure.
            • No support for different charsets. Events are not always in client's character set.
              Should conversion be done automatically by library?
            • No any kind bound checking when reading events.
              Something like CHECK_SPACE in log_event.cc I guess.
            • better split mariadb_rpl_fetch-method to smaller pieces for easier unit testing.
              Function is "hardcoded" to ma_net_safe_read.
            • ROW replication TABLE_MAP parsing totally missing so far..

            I could do some of these things or is there something already happening somewhere?
