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install_gpt no longer exists, and has been replaced by cgpt.py's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.
