For reading UDF label and UUID is needed blkid >= 2.30. For creating new
UDF filesystem is needed mkudffs binary from the udftools package.
When creating new UDF fileystem, revision 2.01 for hard disk media is used.
Therefore it is not possible to use it for optical (or other) medias.
Problems:
* Check for min and max capacity is incorrect as it depends on logical
(sector) size of the disk.
* Check for max label length is incorrect too as it depends on characters
itself in label.
* Specifying label is not working yet as FileSystem::create() does not get
label parameter.
* UDF filesystem should be used on unpartitioned disk, without MBR or GPT
and spanning whole disk, but KDE Partition Manager does not support it.
* When MBR is used, MBR partition id should be 0x07, but currently it is
incorrect 0x83. See: https://serverfault.com/a/829172 (same for GPT)
