[PATCH v2 2/2] decimal: expose decimal type to lua.

[Vladimir Davydov]

The patch looks good, but you haven't covered all error cases in

Please make sure there's no red lines.

Also, I asked you during the previous review iteration, but you seem to
have overlooked it: can we please do anything about the trailing spaces?
