Fix for bug 7894 replaces a field(s) in a non-aggregate function with a item
reference if such a field was specified in the GROUP BY clause in order to
get a correct result.
When ROLLUP is involved this lead to a wrong result due to value of a such
field is got through a copy function and copying happens after the function
evaluation.
Such replacement isn't needed if grouping is also done by such a function.

The change_group_ref() function now isn't called for a function present in
the group list.

The Item::split_sum_func2 method should not create Item_ref
for objects of any class derived from Item_subselect.

Any default value for a enum fields over UCS2 charsets was corrupted
when we put it into the frm file, as it had been overwritten by its
HEX representation.
To fix it now we save a copy of structure that represents the enum
type and when putting the default values we use this copy.

statement that uses an aggregating IN subquery with 
HAVING clause.
A wrong order of the call of split_sum_func2 for the HAVING
clause of the subquery and the transformation for the 
subquery resulted in the creation of a andor structure
that could not be restored at an execution of the prepared
statement.

 VALUES() was considered a constant. This caused replacing 
 (or pre-calculating) it using uninitialized values before the actual
 execution takes place.
 Mark it as a non-constant (still not dependent of tables) to prevent
 the pre-calculation.

            1003: Incorrect table name
in multi-table DELETE the set of tables to delete from actually 
references then tables in the other list, e.g:
DELETE alias_of_t1 FROM t1 alias_of_t1 WHERE ....
is a valid statement.
So we must turn off table name syntactical validity check for alias_of_t1 
because it's not a table name (even if it looks like one).
In order to do that we add a special flag (TL_OPTION_ALIAS) to 
disable the name checking for the aliases in multi-table DELETE.

The problem is that on some Mac OS X-es the file writing/reading
call with zero bytes to read/write returns error.
So here i try to eliminate that kinds of calls.
