Execute a BINLOG statement
TODO: This currently assumes a MySQL 5.x binlog.
When we'll have binlog with a different format, to execute the
BINLOG command properly the server will need to know which format
the BINLOG command's event is in. mysqlbinlog should then send
the Format_description_log_event of the binlog it reads and the
server thread should cache this format into
To execute the BINLOG command properly the server needs to know
which format the BINLOG command's event is in. Therefore, the first
BINLOG statement seen must be a base64 encoding of the
Format_description_log_event, as outputted by mysqlbinlog. This
Format_description_log_event is cached in
rli->description_event_for_exec.
