* Add hooks to ubuntu-cpc to divert /bin/sync in the chroot and undivert it
at the end. This is a general-purpose change that should be applied to
all flavors and archs, but at the moment it's only needed on armhf+raspi2
to work around the raspberrypi2-firmware postinst calling sync, which is
actually warranted in the normal case.
* If a subarch is specified for a cloud image build, don't build rootfs
artifacts; these should come from the 'generic' build.
* Fix architecture handling in hooks. We know we're always being invoked
from a launchpad-buildd-like setup, which passes ARCH and SUBARCH in the
environment, because auto/config and auto/build both rely on this. So
don't scatter dpkg --print-architecture calls throughout, especially
when many of these are not cross-build-aware.
* Refactor ubuntu-cpc hooks to allow us to handle images where the root
partition should not be partition 1.

* ubuntu-cpc: fix hooks/032-disk-image.binary call to
create_empty_partition, which requires five args due to "-u"
* ubuntu-cpc: in hooks/030-root-tarball.binary create /lib/modules to fix
(LP: 1543204).

* Refactor ubuntu-cpc hooks to always produce a 'plain' rootfs via
live-build and reuse this for the tarball, instead of lb_binary_rootfs
creating some artifact that we ignore / throw away.
* Initial support for raspi2 subarch.
* Import live-build/ubuntu-cpc/hooks/raspi2/mkknlimg from
https://github.com/raspberrypi/linux/blob/rpi-4.1.y/scripts/mkknlimg
and use it to install a bootable uboot.bin.
* ubunutu-cpc:
- extended hooks/functions to support creation of derivative images
including mounting images.
- added the ability to create qcow2 images in hooks/functions
- simplified loop clean-up in hooks/functions
- removed assumption that disk1.img would be built
- switched qcow2 generation to use hooks/functions function
