The Blackhole engine did not support row-based replication since the delete_row(), update_row(), and the index and range searching functions were not implemented. This patch adds row-based replication support for the Blackhole engine by implementing the two functions mentioned above, and making the engine pretend that it has found the correct row to delete or update when executed from the slave SQL thread by implementing index and range searching functions. It is necessary to only pretend this for the SQL thread, since a SELECT executed on the Blackhole engine will otherwise never return EOF, causing a livelock.
