Revert "add bash-4.2 patches 25 through 39"

This reverts commit b6c5b9806f6ae79652336a7cfb51fe0f03d0590a.
use recursivePthLoader instead of setuptoolsSite
prefix setuptools -> python-setuptools
release-python.nix used by hydra python-rework jobset

define full job attributes (not just systems) so we can define
schedulingPriority without touching release-lib.nix.

There is definitely a more elegant way to recursively walk attributes
and fill in missing values (job and schedulingPriority).
Merge https://github.com/jcumming/nixpkgs into master_clean
remove site.py files

setuptools site.py can't resolve recursively which is needed for nix,
as each package has its own directory. A different solution than
putting the loader into every package output needs to be found.

see also #209
python-modules: remove long non-functional propagated-user-env-packages

we use recursive processing of pth files instead
do not create e.g pth file for build inputs

if they are really needed they will be in pth file created by
easy_install. If that does not work, they need to be put into
propagatedBuildInputs or the setup.py fixed.

see #210
don't propagate recursivePthLoader, it is needed to process it already
python manpages as python2.6, python2.7 and python
