[SPARK-12798] [SQL] generated BroadcastHashJoin
A row from stream side could match multiple rows on build side, the loop for these matched rows should not be interrupted when emitting a row, so we buffer the output rows in a linked list, check the termination condition on producer loop (for example, Range or Aggregate).
Author: Davies Liu <davies@databricks.com>
Closes #10989 from davies/gen_join.
