Make use of the new partition UUIDs for ROOT-A and ROOT-B in the root=
kernel parameters provided by the legacy (non-kexec) bootloaders. This
makes all of our images bootable as-is without having to pass them
through image_to_vm.sh. :-D
Before we can switch from using device names in root= to partition table
UUIDs we need some values that will remain consistent across upgrades
since the partition table is not updated when filesystems are.
As outlined here we need a new partition layout, this patch makes the
necessary changes:
https://groups.google.com/forum/#!topic/coreos-dev/bA7gwGGoTng
The first big change is making all of the scripts obey partition numbers
based on labels in the disk_layout.json. This makes it much easier to
change later on.
The second big change is in the layout itself. The json file was updated
to reflect the document above.
And finally the grub boot configuration needed for pv-grub and pygrub
were added to the create_legacy_bootloader_templates.sh library utlity.
Everything seems to work and boot now.
We are coming close to filling the rootfs size, so just make it bigger.

This change adds support for building the disk layout from a
configuration file. It also cleans up much of the image creation
code.
install_gpt no longer exists, and has been replaced by cgpt.py's
write action. This spits out a file that has two functions that can
be called to write a partition layout to a disk/file. This gets rid
of the gigantic nest of calculations that built the layout previously.
All instances of partition/filesystem sizes in build scripts should now
be gone in favour of calls to the cgpt.py tool.
create_boot_desc has moved inside the base image creation, in an effort
to simplify build_image.
load_kernel_test is gone since it's apparently not supposed to be called
here anyway (asked wfrichar/rspangler about this one).
Base image creation now uses files rather than loop devices when
building an image. This means we can simply umount them once we're
done and not worry about cleaning up the loop device, since it's
been done for us.
Hash pad calculation has been removed. This is now set manually inside
the partition config file.
Hybrid MBR creation is gone, since it's now possible to do that in a board
specific hook (see overlay-beaglebone/scripts/board_specific_setup.sh).
OEM partition now has a filesystem, which is mounted at /usr/share/oem
during emerge so that packages can stash files here.
root_fs_dir and friends are still globals, but the long-term idea
is to make this not the case.
