When changing the size of the stateful partition, we must be able to
operate on any image, with any arrangement of partitions. The static
templates cannot be used because we don't know what we're starting with.
As such, this change makes the update function walk the list of
partitions, duplicating all their details, and moves any located after
stateful by the change in size, and copies in the new stateful contents.

The "update_partition_table" routine is used by mod_image_for_recovery.sh
and ~/trunk/src/platform/dev/host/tests/mod_recovery_for_decryption.sh.
This moves the routine into a common location so future changes will not
break things. Additional removes the duplicate okboat/failboat
definitions from mod_image_for_recovery.sh since those are in a common
place already.
This change does not fix the stateful resize logic part of the bug, but
does move the code into a single place so mod_recovery_for_decryption.sh
can use it once it has been fixed.

Looks like the func was copy & pasted, so delete the first one (which
doesn't get used). Then expand on the existing func to also generate
a mount and an umount script.

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install_gpt no longer exists, and has been replaced by cgpt.py's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