The old script was heading towards spaghetti code realm. This breaks up all the image variations such as hybrid MBR, OEM packages, etc into configuration options and small functions that actually do the work. All this is in the new vm_image_util.sh library but the command line parsing and overall procedure remains in image_to_vm.sh As part of this we gain support for putting some qemu options in a config file as well as Xen virtual machines using pygrub and pvgrub. Lots of generally unused options have been removed to simplify things and keep output file names consistent.
