- Do not hardcode build artifact names.
- Download build artifacts to their own subdirectory for multilayer images
- Keep backward compatibility with "flat" images
- Add boot option layerfs-path for images that support casper to boot multilayer images

This needs rebased against current trunk - in particular, revno 2014 introduces changes to add handling of hwe squashfs in addition to generic, which I noticed because the squashfs-generic handling in your branch doesn't handle the other possible kernel flavors that I expected it to.
