I never intended this, but people started using fuse to implement block device
based "real" filesystems (ntfs-3g, zfs).

The following four patches add better support for these kinds of filesystems.
Unlike "normal" fuse filesystems, using this feature should require superuser
privileges (enforced by the fusermount utility).

Thanks to Szabolcs Szakacsits for the input and testing.

This patch adds a 'fuseblk' filesystem type, which is only different from the
'fuse' filesystem type in how the 'dev_name' mount argument is interpreted.
