Fixed lp:944422 "mysql_upgrade destroys Maria tables?"

The issue was that check/optimize/anaylze did not zerofill the table before they started to work on it.
Added one more element to not often used function handler::auto_repair() to allow handler to decide when to auto repair.


mysql-test/suite/maria/r/maria-autozerofill.result:
  Test case for lp:944422
mysql-test/suite/maria/t/maria-autozerofill.test:
  Test case for lp:944422
sql/ha_partition.cc:
  Added argument to auto_repair()
sql/ha_partition.h:
  Added argument to auto_repair()
sql/handler.h:
  Added argument to auto_repair()
sql/table.cc:
  Let auto_repair() decide which errors to trigger auto-repair
storage/archive/ha_archive.h:
  Added argument to auto_repair()
storage/csv/ha_tina.h:
  Added argument to auto_repair()
storage/maria/ha_maria.cc:
  Give better error & warning messages for auto-repaired tables.
storage/maria/ha_maria.h:
  Added argument to auto_repair()
  Always auto-repair in case of moved table.
storage/maria/ma_open.c:
  Remove special handling of HA_ERR_OLD_FILE (this is now handled in auto_repair())
storage/myisam/ha_myisam.h:
  Added argument to auto_repair()
