* Added ShadowPartitionChanged() to KDiskSystem and respective hooks

to the module interfaces. So the disk system will be informed, when a
  shadow partition has changed and it is allowed to do necessary
  adjustions (e.g. adjusting the cookie, the parameters, or on
  partitioning system initialization even creating special child
  partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
  partitioning system can report at which index the new child shall be
  inserted.
