It shouldn't be possible to link multiple productseries to a sourcepackage in a given distroseries

Bug Description

The unique constraint specified on the Packaging table is
(distroseries, sourcepackagename, productseries).

I think this should really be (distroseries, sourcepackagename). I don't think it makes much sense to allow linking multiple productseries to a sourcepackage. Since there will be only one active link at a time (otherwise, they'll be different sourcepackagenames).

The wrong constraint causes problems:

1. SourcePackage.direct_packaging and SourcePackage.packaging only returns one result, where there should really be way to return the set.
2. Reload several time the +index page of a sourcepackage with multiple productseries link and you'll get a different one each time. Example:

If the historical trail is important, we should add an active boolean flag (or model that state through the packaging column). And only allow one active link.

This is the underlying cause of bug #352374. I think we can fix that bug by deleting the bad link. But it would be better if this non-sense never happened.

There are 81 bad packages in staging. I think we can clean fix this constraint, then fix the bad package

The <productseries>/+packaging link allows the user to select any distroseries and any legitimate sourcepackagename regardless of if distroseries already has that package linked.

Once the mistakes is made, any attempt to fix the problem via the UI will cause an oops (bug #352374)
    Retry: duplicate key value violates unique constraint "packaging_uniqueness"

While it is possible to transfer the bad package to another project and series without packaging it cannot be deleted (bug #193469)

Trying to correct this from +addpackaging by leaving an empty sourcepackagename causes an oops (bug #344376) because
the form is not smart enough to know it is required

The user may create multiple packages for different productseries in the same distroseries, which causes two idential packages to be listed in the project page (bug #379017)
