Beginning of Disk Device API:

* Made all headers parsable. Also some smaller changes.
* Added empty source files for new classes.
* Changed obsolete implementations of existing classes, so that we
  now have basic functionality for BDiskDevice[Roster] and BPartition.
  Iterating through disk devices works and the data we get doesn't look
  too bad for the beginning.
