ONLY UPDATE IF YOU NEED THIS (i.e. Andreas probably will)

- more fixes for 2.5 builds, much overlap with Andreas' check in from
  yesterday.

- add vfs_inode to Lustre inode info: for 2.5 this makes this the
  whole inode.

- two versions of intent_release: Robert's and the new one for 2.5

- Robert's patch - so this may break some stuff, we'll sort that out.

- convert device numbers

- small fixes to make thread handling compatible with 2.5

- always compile super25.c and super.c; the contents is conditional on
  the version
