Description:
When truncating a partitioned MyISAM table, its auto_increment value is not reseted. (It works in InnoDB and Falcon)

How to repeat:
CREATE TABLE t1 (c1 INT AUTO_INCREMENT PRIMARY KEY)
ENGINE=MyISAM
PARTITION BY HASH (c1)
PARTITIONS 2;
INSERT INTO t1 VALUES (NULL);
SELECT * FROM t1 ORDER BY c1;
c1
1
DELETE FROM t1;
INSERT INTO t1 VALUES (NULL);
SELECT * FROM t1 ORDER BY c1;
c1
2
TRUNCATE TABLE t1;
INSERT INTO t1 VALUES (NULL);
SELECT * FROM t1 ORDER BY c1;
c1
3
DROP TABLE t1;
# the result should be 1,2,1 not 1,2,3.

Suggested fix:
Implement the ha_myisam::reset_auto_increment() function, which could be called from ha_partition::reset_auto_increment via handler::ha_reset_auto_increment.
Or do this in the ha_myisam::delete_all_rows (mi_delete_all_rows) if SQLCOM_TRUNCATE like InnoDB does.

      Bug#35111: Truncate a MyISAM partitioned table does not reset
      the auto_increment value
      
      Problem was that a non partitioned table just did recreate of the table,
      overwriting the previous table. But a partitioned table could not indicate
      if the partitioning engine (or the partitions engines) did support recreate
      or not.
      
      Solution was to extend the 'peek at the table' function (mysql_frm_type) to also
      look at the default engine used by the table, resulting in the same handling of
      partitioned as of non partitioned tables.

      Bug#35111: Truncate a MyISAM partitioned table does not reset
      the auto_increment value
      
      This is an alternative patch that instead of allowing RECREATE TABLE
      on TRUNCATE TABLE it implements reset_auto_increment that is called
      after delete_all_rows.
