- Program drbl-list-tarball was added to replace list_available_tbz2 and list_latest_tbz2.
- Program drbl-prepare-pxelinux and the function get_syslinux_binary_for_dos_linux of drbl-functions was modified to use syslinux xz tarball instead of bz2 tarball because the latest testing one does not provide bz2 format anymore.
