Switch live filesystem building to live-build
Ubuntu live CD builds have always been based on an in-house tool called livecd-rootfs. Since we started Ubuntu, Debian has also been working on live CDs, and has a tool called live-build which is capable of building Ubuntu images as well. There is little sense in maintaining two separate tools, so since live-build is more flexible we should switch to it.

(Note that "done" indicates either "working sufficiently well for Ubuntu and forwarded to a Debian bug" or "committed somewhere other than live-build" (e.g. wrapper code in livecd-rootfs). It doesn't necessarily mean that the patch has been accepted into Debian, and there may be more work required to make patches acceptable.)
