b6bee0a394 BUG#21166: Prepared statement causes signal 11 on second execution
Changes in an item tree done by optimizer weren't properly
registered and went unnoticed, which resulted in preliminary freeing
of used memory.

15b591561f A fix and a test case for Bug#16248 "WHERE (col1,col2) IN ((?,?))
gives wrong results". Implement previously missing 
Item_row::cleanup. The bug is not repeatable in 5.0, probably 
due to a coincidence: the problem is present in 5.0 as well.

Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933)

79ec81071a Better bugfix for "HAVING when refering to RAND()" (Bug #8216)
Ensure that references in HAVING, ORDER BY or GROUP BY are calculated after fields in SELECT.
This will ensure that any reference to these has a valid value.
Generalized the code for split_sum_func()

3ceb04a5d8 Merge of fix for BUG#6976 continued: pulling in some Item_ref changes from 5.0
* Added Item_ref::set_properties 
 * Item_ref::Item_ref now expects to get in *item either
     NULL - then fix_fields() will be called later  or 
     ptr to Item it will refer to - then an equivalent of fix_fields() call is performed

9ed8cd701b Merging fix for BUG#6976 from 4.0 to 4.1
The problem in 4.1 was the same as in 4.0 - fix_fields() not called for created Item_ref. 
The fix is similar too - initialize Item_refs in ctor (but don't interfere with cases when 
Item_ref is used by subselects).

3938ac5436 This ChangeSet Introdices Item_equal.
The objects of this class represent multiple conjunctive equalities
in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn.
The objects are used to generate new possibale paths to access
the tables when executing a query.
They are also used to optimize the execution plan 
chosen by the optimizer for the query.
