Fixed bug#16272: IF function with decimal args can produce wrong result
The Item_func_if::fix_length_and_dec() function when calculating length of
result doesn't take into account unsigned_flag. But it is taken when
calculating length of temporary field. This result in creating field that
shorter than needed. Due to this, in the reported query 40.0 converted to 9.99.
The function Item_func_if::fix_length_and_dec() now adds 1 to the max_length if
the unsigned_flag isn't set.
