The source of the problem is in Field_longlong::cmp. If 'this' is an unsigned number, the method casts both the current value, and the constant that we compare with to an unsigned number. As a result if the constant we compare with is a negative number, it wraps to some unsigned number, and the comparison is incorrect. When the optimizer chooses the "range" access method, this problem causes handler::read_range_next to reject the current key when the upper bound key is a negative number because handler::compare_key incorrectly considers the positive and negative keys to be equal. The current patch does not correct the source of the problem in Field_longlong::cmp because it is not easy to propagate sign information about the constant at query execution time. Instead the patch changes the range optimizer so that it never compares unsiged fields with negative constants. As an added benefit, queries that do such comparisons will execute faster because the range optimizer replaces conditions like: (a) (unsigned_int [< | <=] negative_constant) == FALSE (b) (unsigned_int [> | >=] negative_constant) == TRUE with the corresponding constants. In some cases this may even result in constant time execution.

Remove changes made by bug fix #8147. They strips list of insert_table_list to only insert table, which results in error reported in bug #9728. Added flag to Item to resolve ambigous fields reported in bug #8147.
