Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable

a7b877df78 Bugs#9129: CHARSET(), COLLATION(), COERCIBILITY() 
not always correct for NULL values.
Now they always result a non NULL value even
the argument is NULL. It is more usefull for

7e8e033290 type_blob.result, func_system.result, func_str.result, ctype_collate.result: 
fixing test results accordingly.
func_system.test:
  New test that illegal mix of collations does not happen anymore.
item_strfunc.h:
    safe_charset_converter() was added for system constants.
item_strfunc.cc:
  safe_charset_converter() was added for system constants.
item_func.cc, item.h, item.cc:
  Bug#8291: Illegal collation mix with USER() function.
  After discussion with PeterG and Serge, a new coercibility
  level for "system constants" was introduced, between
  COERRIBLE and IMPLICIT. Thus:
  SELECT col1 = USER() FROM t1; - is done according to col1 collation.
  SELECT 'string' = USER(); - is done according to USER() collation.
  At the same time, "nagg" and "strong" members were removed as unused.
item_create.cc:
  Version is a system constant too.

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.

* 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.
