d65678678e Move dib-run-parts into diskimage-builder
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.

7446c32197 Move diskimage-image-create to an entry point
It has always been a weird thing that dib is a python package, but
is totally driven by the disk-image-create script.  It creates this
strange division that is hard to explain.

This moves disk-image-create to a regular python entry-point

Currently, this simply exec()s the original disk-image-create script.

However, we now have a (private) interface between disk-image-create
written in python and the driver shell script.  Here's some things we
could do, for example:

* Argument parsing is generally nicer in Python, and then end result
  is mostly just setting environment variables to flag different things
  in the shell script.  I could see us moving the argument-parsing into
  diskimage_builder.disk_image_create:main() and just setting things in
  os.environ before the exec()).

* I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in
  disk-image-create by calling-back to element-info.  We can just call
  element_dependencies.find_all_elements() in here an export is to
  os.environ before disk-image-create starts.

* remove need for ramdisk-image-create symlink by just exporting
  IS_RAMDISK based on sys.argv[1] value

* you could even unit test some of this :)

97c01e48ed Move elements & lib relative to diskimage_builder package
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__.

91b431ce78 Move element-info to a standard entry-point
Move element-info from a wrapper script to a standard entry-point
console_script.

Update the documentation to explain how to run it for development.  I
don't think we should support the idea that you can check-out the code
and run ./bin/disk-image-create -- it has dependencies (dib-utils,
etc) and needs to be run from a virtualenv (this is what CI in the
gate does).  A follow-up can clean-up some of the path munging stuff
we have for this in disk-image-create.

3d48a528c1 Refactor: block-device handling (local loop)
Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.

This patch factors out the creation and deletion of the local
loop image device handling into a python library.

The main propose of this patch is to implement the needed
infrastructure.  Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

8d052a54a7 Turn docs warnings into errors and fix issues
Set the pbr option 'warnerrors' to make build_sphinx turns warnings into
error. Fix all warnings.

`tox -edocs` will thus abort whenever someone introduce a new error.

644598941c Use dib-run-parts from dib-utils
Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.

This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.

08f5d4997e Remove hardcoded version.
We use semantic versioning, not pbr's pre-version facility. This
line causes local package builds to have the wrong version, and
pbr will in future detect this and error.

f961d745e3 Add dib-lint script
This will provide a place to put checks that catch common errors
in elements.  To start, this just checks that files starting with
a shebang are chmod +x so they can actually be run.

78ec39a711 Update from requirements
The specifically desired change is the one to setup.py which removes the
reference to d2to1. d2to1 is very undesirable to consume due to its
explicit dependency on distribute that is still unfixed. While we're
doing it, go ahead and do the full update.py from requirements.txt to
reduce later churn.

d6deb9f565 Package dib-run-parts
dib-run-parts is a symlink into the elements directory.

During packaging the symlink is preserved however
during installation dib-run-parts becomes a file containing
the contents of the symlink target.

Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.
