ma_test_loghandler_pagecache-t on Windows.


storage/maria/ma_control_file.c:
  stat() is unreliable on Windows (does not reflect process' own writes)
storage/maria/ma_loghandler.c:
  translog_set_lsn_for_files() didn't close its file descriptor; it was
  a real problem as non-closed files could not be purged.
  Same for translog_truncate_log() in case of error.
