diskimage-builder usually provides defaults that work out of the box.
One default that does not work outside of x86 land is Ubuntu distro
mirror url. Considering there are only two valid default options, we can
automatically choose a better default.
This patch changes behavior only for architectures known to be using
http://ports.ubuntu.com/ubuntu-ports. All others still would use
http://archive.ubuntu.com/ubuntu as default. It provides some guarantee
that we do not introduce a regression.

We somewhat discussed skipping qcow2 generation previously in
I9372e195913798a851c96e62eee89029e067baa1. As recent issues with PPC
testing have shown, we are not actually testing the "vm" element and
hence the bootloader path in the functional tests.
I don't think we need to test this on every element; it overlaps
somewhat with the testing done by the nodepool jobs which build full
images and boot them. I also didn't want to introduce a separate run
for this. Thus it seems valuable to at least have one element
enhanced to do this installation and conversion in our default tests
for basic sanity.
This disables qcow generation by default, as per the other change, but
allows an element to drop a file that will override the output
formats. The Xenial element is modified to produce a qcow2 using
this, and also introduces a dependency on the "vm" element so it tries
to install the bootloader.
We now exit if the .qcow2 fails to build as well.

Add a default PPC block-device layout. I've extracted this into
separate yaml files for ease of editing and to facilitate things like
longer comments.
This is not sufficient to get PPC images working, but it is required.

Sphix 1.5 (I9e7261c4124b71eeb6bddd9e21747b61bbdc16fa) includes
"warning-is-error" which supersedes pbr's warnerrors. Enable this and
fix up the resulting failures
- trailing lines for lists in element_deps directive
- missing README's that are linked
- syntax error and highlighting in building instructions

99-squash-package-install in the package-installs element does not
know which python environments the requirements were installed into.
This can cause it to select the wrong python to run the
package-installs-squash script.

On Debian Jessie and Debian Stretch systemctl is in /bin.
If the package systemd-sysv is not installed the script
dib-init-system did not find the init system.
This patch fixes the problem: it also looks in /bin
for systemctl and if found decides for systemd.

The architecture-emulation-binaries element does for a limited number
of architectures on Ubuntu exactly the same as `qemu-debootstrap`.
`qemu-debootstrap` comes in the qemu-user-static package that is
anyhow used when cross-building an image.
This patch replaces the complete architecture-emulation-binaries
element with a call to qemu-debootstrap.

Depending on the types of deployment (security, nfv...) some extra
kernel flags are needed on the images. This change exposes the
DIB_BOOTLOADER_DEFAULT_CMDLINE parameter, defaulting to the
existing 'nofb nomodeset vga=normal', that will allow to modify
these boot params.

Looks that the special handling for Ubuntu is not needed any longer
(its a pity that there are no detailed comments...).
The grub2 element is a second implementation of the bootstrap element
- but because there are some features that come only here, e.g. efi
boot, it should be working as long as this is not implemented in the
bootloader element.

Currently there is no description of dependencies in the generated
documentation of the elements: therefore a user of an element does not
know which other elements are automatically included and e.g. which
configuration options are available. In addition there are some
copy&pastes of parts of the README.rst scattered thought different
Ubuntu and Debian specific elements.
This patch adds a semi-automatic generation of dependency information
of all elements. Nevertheless these are not automatically included.
The author of the element's README.rst can decide if and where the
dependency information should appear and can use the descriptor
.. element_deps::
for this.
This patch adds the dependency information for some Debian and
Ubuntu patches - and creates the base for later removing the
duplicated parts.
A call is added to element_dependencies._find_all_elements() to
populate reverse dependencies for Element objects.
(This is a reworking of I31d2b6050b6c46fefe37378698e9a330025db430 for
the feature/v2 branch)

With the old configuration structure it was only possible
to use one image and one partition layout. The new
block-device configuration uses a list at top level;
therefore it is possible to use multiple instances
of each element type.

During the creation of a disk image (e.g. for a VM), there is the need
to create, setup, configure and afterwards detach some kind of storage
where the newly installed OS can be copied to or directly installed
in.
This patch implements partitioning handling.

Move dib-run-parts from dib-utils into diskimage-builder directly.
For calling outside the chroot, we provide a standard entry-point
script. However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element. I believe this to be the KISS approach.
This removes the dependency on dib-utils. We have discussed this
previously and nobody seemed to think retiring dib-utils was going to
be an issue.
This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.
