Improvements:
* When mounting an old file system, CryFS will ask before migrating it to the newest version.
* Operating system tools like the mount command or /proc/self/mountinfo report correct file system type and also report the base directory.
* Reacts correctly to fsync() and fdatasync() syscalls by flushing the corresponding data to the disk.
Version 0.9.4
