* Added back and partially reimplemented the

Browse Source 
K{Disk,File,Partitioning}System writing methods. It is now required
  that the caller has marked the concerned partitions busy, hence we can
  (read-)access them without needing a lock. The module interfaces will
  will be changed to take advantage of the fact as well. The methods take a
  disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
  decided, whether we need it at all or just want to add a special
  handling in the cases where notifications during the operation make
  sense.
* Reimplemented the disk device write support syscalls (save
  _user_move_partition() for which other module hooks are needed). They
  call the KDiskSystem methods, now.
