This patch allows livecd-iso-to-disk.sh to detect if the specified .iso
image is an Anaconda DVD installer. If so, it copies it to the USB disk
and configures syslinux to boot it. Anaconda will automatically find
the DVD iso on the USB stick and install from it.
Requires Fedora 11 Preview DVD iso and later.
* This was tested to with Fedora 11 Preview DVD iso, without breaking
standard LiveCD iso install.
* Code is intentionally not "clean" in order to minimize the size of the
git diff to make it easy to visually understand and confirm the changes.
If this patch is acceptable, it will be followed by another patch that
cleans up the code.
