[gentoo-dev] [PATCHES] python-r1 suite clean up & impl reorder

[Michał Górny]

Hi,

Here's another patchset. Mostly fixups inspired by multilib-build.eclass
changes with a few little additions.

Changes:

1. eclass-set variables are now read-only,
2. 'unset -f' is used to unset temporary & local functions,
3. implementations are reordered for sane order.

I've tested this with a few dozen random distutils-r1, python-r1,
python-any-r1 and python-single-r1 packages. However, for
the implementation reorder a larger tinderbox run would be appreciated.

As explained in the commit, the reorder may influence files installed by
a package, and implementation selected by python_setup(). This should
not cause issues for correctly written ebuilds, and should help us find
those that are not correctly written ;-).

In other words, we're finally considering Python 3.x preferred over
Python 2.x.

Please review.
