This was done after discussions with Igor, Sanja and Bar. The main reason for removing the deprication was to ensure that MariaDB is always backward compatible whenever possible. Other things: - Added statistics counters, mainly for the feedback plugin. - INTO OUTFILE - INTO variable - If INTO is using the old syntax (end of query)
