By default, pv automatically infers and uses the full width of the
terminal. This generally makes sense for a console application, but in
the case of pv it just causes the progress bar to be ridiculously wide
when run on wide terminals, to the point it's hard to read. This CL is
setting it to 80 characters, the widely accepted standard width for
a terminal, in cases where the terminal appears to be larger than
80 columns. Note that:
* Even with -w, pv appears to be resizing the progress bar as the
terminal width changes midway through the run. This means that if
a user widens the window, then the progress bar will go wide again and
there's nothing to be done about it.
* Theoretically, in very rare cases this may lead to a progress bar the
exceeds the width of the terminal (i.e. set to 80 columns on
a terminal that has just shrunk to fewer columns). The odds for such
timing are close to nil and even then the damage is minimal.
* This will work for non-terminal runs, or otherwise runs where stty
does not produce any output.
* To avoid the initialization overhead for all common.sh inclusion,
replacing the variable with a function that prints the pv/cat command.
BUG=None
TEST=Ran ./image_to_usb on wide and narrow terminal windows, it works.

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install_gpt no longer exists, and has been replaced by cgpt.py's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

Rather than forcing all consumers of DEFAULT_BOARD to remember to call
get_default_board, just do it for them automatically.

A modest number of different scripts and files have a usage
restricted to build_image. Move those files to build_library,
to prevent them accumulating unwanted clients.

This shortens the standard boilerplate for finding and sourcing
shell function libraries for build_image, mod_image_for_test.sh and
mod_image_for_recovery.sh.
As a side effect of the change, both mod_image_for_test.sh and
mod_image_for_recovery.sh will now restart inside the chroot if
invoked from outside; this is consistent with the pre-existing
behavior of build_image.
BUG=None
TEST=run the three scripts, from both inside and outside the chroot
