This is intended to eventually support building musl-libc based images,
which need the musl overlay.

c886c4cbe1 Make preinstall.d more deterministic
Reorders the preinstall, making the order more explicit.  Also dedupes
some folder setup.

Make python changes more reliable
We oneshot emerge without calculating dependencies a few things to solve
for possible dependency loops.

Python 3.5 also became stable, so don't need to do special things for
it.

Matched the uninstall with the install lines (no need for a full if
statement).

Update Gentoo element for element changes
There have been a few changes over the past few months, here we make the
following changes.

* change from backtrack=99 to complete-graph as a more correct flag
* make python version selection more in line with what gentoo supports
* set up python before stuff gets pip installed
* ensure we have the proper pip so we can install pip packages as root
* ensure we have the proper use flags for the disk formatting changes
* set DIB_RELEASE like other distros
* fix openssh-server element for gentoo

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__.
