This is the next (and possibly last for now) extension to the /dev/disk 
directory. Limited to disk related entries which allowed a 
straightforward extension of the existing code.

My original idea was to add also other drive letters and volume GUIDs. 
Too complex for now.

Interestingly the volume GUID (by-uuid) for partitions on MBR disks is 
sometimes identical to the partition "GUID" (by-partuuid), sometimes 
(always for C:?) not. With GPT disks, both GUIDs are possibly always 
identical.

I will provide a related new-features doc patch later.
