BUG#13354387 - CRASH IN IN MY_DECIMAL::OPERATOR FOR VIEW AND FUNCTION UNIX_TIME
Fixing the 5.5 part (the 5.6 part will go in a separate commit soon).
Problem:
Item_direct_ref::get_date() incorrectly calculated its "null_value",
which made UNIX_TIMESTAMP(view_column) incorrectly return NULL
for a NOT NULL view_column.
Fix:
Make Item_direct_ref::get_date() calculate null_value
in the similar way with the other methods
(val_real,val_str,val_int,val_decimal):
copy null_value from the referenced Item.
