Fixed a bug: InnoDB could make the index page directory corrupt in the first B-tree page splits after mysqld startup. A symptom would be an assertion failure in page0page.c, in function page_dir_find_slot().

Fixed a bug: InnoDB could in rare cases return an extraneous row if a rollback, purge, and a SELECT coincided.

Fixed a possible hang over the btr0sea.c latch if SELECT was used inside LOCK TABLES.

Fixed a bug: If a single DELETE statement first managed to delete some rows and then failed in a FOREIGN KEY error or a Table is full error, MySQL did not roll back the whole SQL statement as it should.
