The current code cares about filenames, but it's too fragile, we have
to check the path is really path to the block device.

.. after many many years it seems that we can follow libc code rather
than duplicate realpath(3) implementation.

* lib/canonicalize.c: don't interpret empty strings as relative paths
* libmount: more robust libmnt_table find function and debug messages

It's overkill to modify unknown paths in a generic function like
canonicalize_path().
for example:
mount -t fuse 'sshfs#marty@thee:/' /media/thee
will be canonicalized to
mount -t fuse 'sshfs#marty@thee:' /media/thee
and this obvious bug.

* mount(8) uses private device-mapper names in mtab
* libblkid returns private device-mapper names when evaluate udev
/dev/disk-by symlinks.
* on systems where DM is fully integrated with udev the /dev/mapper/<name>
files are symlinks to /dev/dm-N. It means we need a special care to hide
private device-mapper names.
