* Moved GetNextSupportedType() and IsSubSystemFor() from

BDiskSystem to BPartition and reimplemented them using the userland
  add-on backend instead of syscalls. As a side effect this solves the
  TODO I recently added in GetNextSupportedType().
* Reimplemented BDiskSystem::GetTypeForContentType() using the userland
  add-on backend instead of a syscall.
* Moved GetTypeForContentType() and IsSubSystemFor() from
  BPartitionHandle to BDiskSystemAddOn. They were misplaced.
