Merge ~cjwatson/launchpad:built-using-model into launchpad:master

[Colin Watson]

Parse Built-Using fields from uploaded binaries

These are parsed into a form that we'll later be able to use in the dominator, with the goal of keeping source publications that are referenced by Built-Using fields in active binary publications.

The most complicated bit is working out which source package releases a given Built-Using field refers to, since there are edge cases where just the name and version can be ambiguous. We do the best we can by following the archive dependencies of the build and finding sources that it could plausibly have used.

Unresolvable entries in Built-Using, including ones that refer to deleted source publications, will result in binary uploads being rejected.

Explicitly check "build.current_component is None"

This can happen in tests, especially of gina, and the resulting crash is
a bit confusing, so let's raise a clearer exception in this case.

fde0f10... by Colin Watson on 2020-04-17

Preserve original Built-Using fields for publication

We aren't sure whether apt will get confused if the exact serialisation
(e.g. ordering) of Built-Using in Packages differs from that in the
package's control file, so let's preserve it rather than trying to
reconstruct it.

0692e86... by Colin Watson on 2020-04-17

Don't consider SPPH.status when creating BSRs

We don't normally treat SUPERSEDED differently from DELETED in this sort
of situation, and at that point it isn't really worth checking the
status at all.

a4163e3... by Colin Watson on 2020-04-20

Add more vertical whitespace

7ca1f32... by Colin Watson on 2020-04-21

Limit Built-Using references to the same archive and series

Allowing cross-archive references makes the dominator's job harder, as
well as permitting non-consensual pinning of sources to the Published
state in foreign archives. Forbidding such references may be confusing
in some cases, but seems likely to be less bad than the alternative.

8983670... by Colin Watson on 2020-04-21

Refactor createFromRelationship using Archive.getPublishedSources

Now that we're only considering a single archive, this is equivalent and
much clearer.

e9bb481... by Colin Watson on 2020-04-22

Add BinarySourceReference.createFromSourcePackageReleases

This makes some tests (especially in branches further up this stack)
more convenient.

What is the possible 'unfortunate apt behaviour'?

Clarify "unfortunate apt behaviour"

4f4c880... by Colin Watson on 2020-04-23

Give IBinaryPackageRelease.built_using_references a value_type

[Colin Watson (cjwatson)]

I've clarified this.

[Tom Wardill (twom)]

The model and implementation for this seem to make sense. I'm not entirely fluent in apt behaviours, but this LGTM :).
