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()

064c73490b Fix for BUG#7455. 
The fix checks if the trim string argument is NULL. If so, the standard
mandates that the function result must be also NULL.

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).

4b0882e0a6 Fix for bug #6765 "Implicit access to time zone description 
tables requires privileges for them if some table or column level grants
present" (with after-review fixes).

We should set SELECT_ACL for implicitly opened tables in 
my_tz_check_n_skip_implicit_tables() to be able to bypass privilege
checking in check_grant(). Also we should exclude those tables from
privilege checking in multi-update.
