it couldn't entirely write its new information (it could not write
more bytes than the old format wrote).


storage/maria/ma_control_file.c:
  Let ma_control_file_write_and_force() return error if called when
  file is not open.
  When the file was of an old version (no room for our changeable part)
  we upgrade this part. When the file was of a new version we re-use its
  format but zero the parts which we can't maintain.
storage/maria/ma_init.c:
  ma_control_file_write_and_force() now does not assert if called
  when control file is not open.
storage/maria/ma_recovery.c:
  missing ";" (thanks Peter Zaitsev for the bug report and Monty for the patch)
