f78a60593a Fix for BUG#6976: 
In Item_ref::Item_ref set maybe_null (and other fields fix_fields sets) to be the 
same as in (*ref), because Item_ref::fix_fields() will not be called.  Previously 
maybe_null was 0 always and this produced a bogus state where 
maybe_null==0 && is_null() == true 
which broke evaluation for some upper-level Items, like AND and OR.

41eda1c949 Revert patch for bigint handling in double context as it broke normal bigint handling 
The right way to fix this is to change the Field::store(longlong) method to be
Field::store(longlong, bool unsigned_flag), but this is better to do in 4.1 than in 4.0
