1. Let shell function "rootfs_install_packages" support incremental deb
image generation. The following is the design:
1) If deb incremental generation is supported:
1) Compare solution manifest with previous installed manifest to dump
unused package names and remove them.
2) Compare three manifests to dump updated packages and reinstall them.
2) Install packages as solution manifest lists.
3) Change solution manifest to installed manifest for next image session.
4) Back up dpkg database for next image session.
2. Add checks for the creation of symbolic link "${IMAGE_ROOTFS}${opkgli-
bdir}/info" and "${IMAGE_ROOTFS}${opkglibdir}/status".
