This changes the disk image for both USB keys and hard-drive installs to use the EFI GUID Partition Tables. This is a prequisite for booting with an EFI BIOS. This change does not use the EFI Boot protocol; it still boots using Legacy BIOS. The PMBR contains syslinux' gptmbr.bin, which searches the GPT for a specified partition's GUID to boot. I've tested it on my EeePC. The USB image works, chromeos-install works, and the reimaged hard drive works. I have not yet tested the memento_updater.sh script, but I wanted to start the review without waiting until it's all perfect. I will also be refactoring build_gpt.sh and chromeos-install to share common logic. It's almost certain that all existing dogfood machines will need to be reimaged from a USB key. We could probably figure out a way to upgrade automatically, but not quickly or without risk. In addition to the GPT formatting, the build_image script has changed to emit a single usb.bin file. This can be copied directly onto a USB key and booted. Installation of dev tools needs to happen with build_image, not image_to_usb. I have not yet looked at the other image_to_* scripts.
