- add field {part_number} for partitions

  (handle it in subpart_from_wild_device_name(), partition_table::read())
- create migrate_device_names() to handle the change of device names when
  changing kernel&modules (eg: hde->hda or hda->sda)
- change prototype of install_any::use_root_part()
  (prefix is dropped, optional $in is added)
- create fs::type::can_be_this_fs_type() and use it
- create devices::part_number() and devices::part_prefix() and use them
