    Inserting a negative value in the autoincrement column of a
    partitioned innodb table was causing the value of the auto
    increment counter to wrap around into a very large positive
    value. The consequences are the same as if a very large positive
    value was inserted into a column, e.g. reduced autoincrement
    range, failure to read autoincrement counter.
    
    The current patch ensures that before calculating the next
    auto increment value, the current value is within the positive
    maximum allowed limit.
