Introduced optimizer switch flag 'optimize_join_buffer_size'.
When this flag is 'off' the size of the used join buffer
is taken directly from the system variable 'join_buffer_size'.
When this flag is 'on' then the size of the buffer depends
on the estimated number of rows in the partial join whose
records are to be stored in the buffer.
By default this flag is set 'on'.
