Create DVDs with xorriso
Use a different approach for building DVDs when xorriso is enabled. The default of using genisoimage is not changed at all. When the config option is set to use xorriso, the actual execution is different between bootable and non-bootable images. The non-bootable images are still created by running xorrisofs (which is a compatibility tool with same UI as genisoimage). Since the image is not bootable, there should be no problems with boot options. For bootable images, Pungi will instead take the boot.iso generated by Lorax, and use xorriso to inject all the extra files into the image. The shell script that used to invoke all the commands to build the ISO now runs the `xorriso` command in interactive mode and feeds another file into it. The new file contains the xorriso commands to add the required files to the image. Signed-off-by: Lubomír Sedlář <lsedlar@redhat.com>
