Several changes to the _kern_{supports,validate}_*() calls:

* Removed the disk_system_id parameter where superfluous.
* Got rid of the `child' variants of the _kern_{supports,validate}_*()
  syscalls for moving and resizing. Reimplemented the real ones to do the
  the right thing, i.e. they check all concerned disk systems now.
* Added _kern_supports_setting[_content]_parameters().
