Some changes are required to support the new ldiskfs2:

- 1.4: modify lconf to support the new fstype.
- 1.6: modify obdfilter to support the new fstype.
- 1.6: modify tunefs.lustre to support changing an existing fs to the new
fstype.
- both: create an ldiskfs2 series and build system based on ldiskfs.
