New Revision: 264995

  Add script to setup bootable CD ISOs for both BIOS and EFI systems. Tested
  and working on QEMU. Actually using this script as the regular image
  generator, like with the memstick one, will require that the kernel support
  EFI too. In particular, the following two things are required:
  1. vt(9) be the default console driver
  2. vt_efifb and vt_vga be able to coexist usefully in the same kernel
  One other note here is that this requires newfs_msdos and mdconfig, which is
  really ugly. NetBSD's makefs at least seems to support FAT now. If that
  actually works, it should be imported and we can get rid of the mdconfig mess.
