There were two problems when inferring the correct field types resulting from
UNION queries.
- If the type is NULL for all corresponding fields in the UNION, the resulting
type would be NULL, while the type is BINARY(0) if there is just a single
SELECT NULL.
- If one SELECT in the UNION uses a subselect, a temporary table is created
to represent the subselect, and the result type defaults to a STRING type,
hiding the fact that the type was unknown(just a NULL value).
Fixed by remembering whenever a field was created from a NULL value and pass
type NULL to the type coercion if that is the case, and creating a string field
as result of UNION only if the type would otherwise be NULL.

HOUR(), MINUTE(), ... returned spurious results when used on a DATE-cast.
This happened because DATE-cast object did not overload get_time() method
in superclass Item. The default method was inappropriate here and
misinterpreted the data.
Patch adds missing method; get_time() on DATE-casts now returns SQL-NULL
on NULL input, 0 otherwise. This coincides with the way DATE-columns
behave.
Also fixes similar bug in Date-Field now.

The problem was that when convert_constant_item is called for subqueries,
this happens when we already started executing the top-level query, and
the field argument of convert_constant_item pointed to a valid table row.
In turn convert_constant_item used the field buffer to compute the value
of its item argument. This copied the item's value into the field,
and made equalities with outer references always true.
The fix saves/restores the original field's value when it belongs to an
outer table.
mysql-test/r/type_datetime.result:
Test for BUG#32694.
mysql-test/t/type_datetime.test:
Test for BUG#32694.
sql/item_cmpfunc.cc:
- Changed convert_constant_item() so that it doesn't destroy the contents
of its field argument when the field originates from table in an outer
query.
Both arguments of the function NAME_CONST must be constant expressions.
This constraint is checked in the Item_name_const::fix_fields method.
Yet if the argument of the function was not a constant expression no
error message was reported. As a result the client hanged waiting for a
response.
Now the function Item_name_const::fix_fields reports an error message
when any of the additional context conditions imposed on the function
NAME_CONST is not satisfied.
mysql-test/r/func_misc.result:

mysql-test/t/func_misc.test:
Added a test case for bug #26545.
The index (key_part_1, key_part-2) was erroneously considered as compatible
with the required ordering in the function test_test_if_order_by_key when
a query with an ORDER BY clause contained a condition of the form
key_part_1=const OR key_part_1 IS NULL
and the order list contained only key_part_2. This happened because the value
of the const_key_parts field in the KEYUSE structure was not formed correctly
for the keys that could be used for ref_or_null access.
This was fixed in the code of the update_ref_and_keys function.
The problem could not manifest itself for MyISAM databases because the
implementation of the keys_to_use_for_scanning() handler function always
returns an empty bitmap for the MyISAM engine.

mysql-test/mysql-test-run.pl:
Add a way to remove options which mysql-test-run.pl no longer uses. Since
mysql-test-run.pl passes unrecognized options through to mysqld directly,
it is not possible to just remove an option. Otherwise it would be given
to mysqld, which probably will not recognize it and will fail to start.
Instead, we now explicitly ignore the option, and print a warning to
the user.

The Item_func_set_user_var::register_field_in_read_map() did not check
that the result_field was null.This caused server crashes for queries that
required order by such a field and were executed without using a temporary
table.

result_field to be not null.
