Tatiana A. Nurnberg c42892d614 Bug#41470: DATE_FORMAT() crashes the complete server with a valid date
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.

mysql-test/r/date_formats.result:
  show that very early dates no longer break DATE_FORMAT(..., '%W')
mysql-test/t/date_formats.test:
  show that very early dates no longer break DATE_FORMAT(..., '%W')
sql-common/my_time.c:
  Allow negative years numbers internally while keeping the interface.
  otherwise if somebody passes year zero for whatever reason, we'll
  get an integer wrap-around that can lead to Really Bad Things further
  down the line. Note that amusingly, calcday_nr() already had signed
  output and calc_weekday() already had signed input, anyway.
