Hello everyone,

Yan Zheng's latest commit redoes the extent back references to make them
more efficient.  This includes a new disk format, so any pulls from the
git unstable trees will have a new disk format to them.

I've bumped the magic in both the kernel and progs repos, so you can't
accidentally mount an FS with the wrong format.

I still hope to finish off compression this week, which will be yet
another format bump.
