------------------------------------
    Attachment: HIVE-13098.WIP.patch

The epic WIP patch... still need to take care of some paths.

Propagating config to all decimals is difficult thanks to massive static use in Hive...

> When e.g. 999999 is selected as decimal(5,0), the result is null. This can be problematic,
esp. if the data is written to a table and lost without the user realizing it. There should
be an option to error out in such cases instead; it should probably be on by default and the
error message should instruct the user on how to disable it.
