Commit message

API to generate package diffs for IDistroSeriesDifferences.

Description of the change

Overview
========
This branch adds the ability to request the generation of package diffs for DistroSeriesDifference objects, and exposes this to the API.

Details
=======
I removed lp.registry.exceptions (which I'd created a few branches ago), after seeing that lp.registry.errors already exists.

Generating the diffs also required adding a base_source_pub attribute to IDSDifference.

Test
====
bin/test -vvm test_distroseriesdifference

What does this demonstrate? Is that a link to the librarian? If so can
you add a comment explaining what it is.

I'm a little bit worried that this test is fragile, after reading some
of the discussions on launchpad-dev about just-in-time configuration
of the librarian, amongst other things. Maybe I got the wrong end of
the stick. Anyway, it seems to me that it's enough just to show that
parent_package_diff_url is not None.

On that note, assertIs(None, ...) and assertIsNot(None, ...) might be
more appropriate for testing against None, but I don't think it
actually matters. Ah, I see you've used it later.

Given that we know the base version was published in the distroseries'
main archive, we can be sure that we can get it back... however, you
prompted me to check getPublishedSources() which only returns
currently PUBLISHED or PENDING sources, which was fine for my tests,
but in reality the base version will be superseded. So I've updated my
tests and refactored this to ensure we return the specific
base-version irrespective of its status. I added a comment too,
explaining why pubs[0] is ok (or why I'd use pubs.one() if it was a
storm result set).
