Support for El Torito without floppy emulation.

        * util/mkisofs/eltorito.c: Include `<errno.h>'.
        (init_boot_catalog): Improve error handling.
        (get_torito_desc): Don't use floppy emulation unless requested by
        user. Patch boot information table when requested via
        `-boot-info-table'.
        * util/mkisofs/iso9660.h (struct eltorito_boot_info): New struct.
        * util/mkisofs/mkisofs.c (use_eltorito_emul_floppy)
        (use_boot_info_table): New variables.
        (OPTION_BOOT_INFO_TABLE, OPTION_NO_EMUL_BOOT)
        (OPTION_ELTORITO_EMUL_FLOPPY): New macros.
        (ld_options): Handle `-boot-info-table', `-no-emul-boot' and
        `--eltorito-emul-floppy'.
        (main): Handle `OPTION_BOOT_INFO_TABLE', `OPTION_NO_EMUL_BOOT'
        and `OPTION_ELTORITO_EMUL_FLOPPY'.
        * util/mkisofs/mkisofs.h (use_eltorito_emul_floppy)
        (use_boot_info_table, get_731): New prototypes.
        * util/mkisofs/write.c (get_731): New function.

* This structure is used to control the output of fragments to the cdrom

* we establish extent numbers for everything, and the second is when we actually
* generate the contents and write it to the output image.
*
* This makes it trivial to extend mkisofs to write special things in the image.
* All you need to do is hook an additional structure in the list, and the rest
* works like magic.
*
* The three passes each do the following:
*
* The 'size' pass determines the size of each component and assigns the extent number
* for that component.
*
* The 'generate' pass will adjust the contents and pointers as required now that extent
* numbers are assigned. In some cases, the contents of the record are also generated.
*
* The 'write' pass actually writes the data to the disc.
