Remove the temporary rootfs.image file and others that are left by build_image and related scripts. Also added tool to emit scripts that can pack and unpack the combined disk image.

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.

This is a short term fix for machines that can't boot a kernel from
the root file system of an SDCard.
This issue depends on issue 602027.

image_to_usb.sh didn't handle the case where the devices were being
automounted.
build_image.sh didn't handle the case where the version string > ~14
characters.

USB image:
- have a stateful partition
- use a read-only system partition
Installer:
- copy read-only system partition from USB to hard drive, skip fsck check
- make stateful partition empty
System:
- Change to tolerate empty stateful partition on bootup
- Don't keep so much of /var on stateful partition (var/lib should be in system
image)
Autoupdate:
- Fix a couple checks to allow partitions 3 and 4 to be system partitions
- Fix a misnomer in mk_memento_images.sh
