Bug#41470: DATE_FORMAT() crashes the complete server with a valid date

Browse Source 
Passing dubious "year zero" in non-zero date (not "0000-00-00") could
lead to negative value for year internally, while variable was unsigned.
This led to Really Bad Things further down the line.

Now doing calculations with signed type for year internally.
