Ian Wienand 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.

Installation
============
If your distribution does not proivde packages, you should install
``diskimage-builder`` via ``pip``, mostly likely in a ``virtualenv``
to keep it separate.
For example, to create a ``virtualenv`` and install from ``pip``
::
virtualenv ~/dib-virtualenv
. ~/dib-virtualenv/bin/activate
pip install diskimage-builder
Once installed, you will be able to :doc:`build images
<building_an_image>` using ``disk-image-create`` and the elements
included in the main ``diskimage-builder`` repository.
Requirements
------------
Most image formats require the ``qemu-img`` tool which is provided by
the ``qemu-utils`` package on Ubuntu/Debian or the ``qemu`` package on
Fedora/RHEL/opensuse/Gentoo.
Some image formats, such as ``VHD``, may require additional
tools. Please see the ``disk-image-create`` help output for more
information.
Individual elements can also have additional dependencies for the build host.
It is recommended you check the documentation for each element you are using
to determine if there are any additional dependencies. Of particular note is
the need for the `dev-python/pyyaml` package on Gentoo hosts.
Package Installation
--------------------
On Gentoo you can emerge diskimage-builder directly.
::
emerge app-emulation/diskimage-builder
