Hello All!

This patch series enhances the ext2 fs backend to also build ext3 and ext4
filesystems, and differentiate between ext2 rev0 and ext2 rev1 filesystems.


Changes v3 -> v4:
  - rebased ontop master for Peter

Changes v2 -> v3:
  - cleanup ext2 dependencies  (Thomas)
  - explain UUID removal  (Thomas)
  - use post-hook to create "ext# -> ext2" symlink  (Thomas, Arnout)
  - drop patch to let fs name the image file extension  (Thomas, Arnout)

Changes v1 -> v2:
  - enhance the ext2/3/4 generation  (Arnout, Peter)
  - allow fs generators to specify the image extension  (Arnout)
  - remove ext2 count- and time-based fsck  (Arnout)


The following changes since commit 2c4ff68e08e063152245d0a1b211df7a4360f925:

Committed series, thanks.

Notice: I did a quick test with a smallish ext4 (3.5MB) filesystem,
where the 1081 blocks extra for the journal wasn't enough, so I've
increased it to 1300 instead.

Strange, Thomas had the same issue, which I was notable to reproduce
here with a basic busybox-only file system (roughly 3.5MiB here too).

Anyway, thanks for the fix up. Indeed, systems going for ext3/4 will
probably not be much impacted by the few extra sectors.
