django/db/__init__.py assumes it is loaded from the filesystem

Description

There is code in the django.db package init.py that lists the available db backends. Unfortunately this code uses os.listdir() on a directory derived from file, and when loaded from a zip archive, this doesn't work. I have a quick hack that works around this, but perhaps there's a better way.

The ticket is marked as 1.0. Not 1.0-beta. We addressed those first. It's still open. We'll get to it. :-)

(In [8424]) Fixed #8238 -- If an invalid database backend is mentioned in settings and the
environment doesn't support os.listdir(), we crashed whilst trying to construct
the friendly error message. This was not so friendly.

This patch handles that case (which occurs in real life in Google App Engine).
Patch from Guido van Rossum.

The load-backend-pep-302 patch use pkgutil.iter_modules instead of os.listdir to solve this.

Thanks for the contribution. Please don't reopen closed for bugs reported and fixed a long time ago with the intention of proposing new features, even when the topics are tightly related. It pollutes ticket history and overall bug tracker stats (e.g. lifetime of tickets)

Open a new ticket for that.
