[PATCH 00/14] Change python-build-system (fixes bug 20765)

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

Hi,

this is a patch-series fixing bug 20765.

Bug 20765 is about problems caused by python packages being installed as
"zipped eggs" (basically these are zip-files).

This series implements what I proposed in
  <http://lists.gnu.org/archive/html/guix-devel/2016-09/msg02021.html>.

A) For python2 include python2-setuptools as a native-input by default.

B) Install Python packages using --single-version-externally-managed

C) Strip python-setuptools and python2-setuptools from all native-inputs
   defined in packages.

Since the first of these changes already make *all* Python packages to be
rebuild, i took the chance to complete points B) and C), too. Step C) is split
into several patches to ease review. I'll happily merge them if requested.
Furhter I did not complete the commit message for these patches. Please
instruct me how these should be written. IMHO there is less use for listing
every singel change liek I did in part 5b.

TODO: by somebody more skilled than me: Take the change and

 * integrate strip-python2-variant into package-with-python2.

 * update Python to 2.7.12 and 3.4.5.

  gnu: ensure pip and setuptools are installed even for Python 2

    --single-version-externally-managed.
