When calculating smooth updateable binaries, filter out cruft binaries from
unstable, because they will not be part of the set of packages that britney
will try to migrate to testing.

Support for binNMUs from *pu is currently broken, so disable it for now.

The parsing of migration items should also look for the suite name in the
architecture part. This fixes the parsing for migration items like
some-src/amd64_tpu and some-src/amd64_tpu/1.0-1

When building the excuses, don't calculate smoothbins for items not from
unstable.
This improves the change from commit db584d9fdc
Also try to make the code more readable.

When building the excuses, don't calculate smoothbins if the source is not in
unstable. Doing so would result in a KeyError and a crash. This happens for
sources that are in testing and (testing-)proposed-updates, but not in
unstable.

Support blocking the removal of a package with a removal hint. This is useful
to block an auto-removal.
Before this patch, only removals for packages not in unstable could be
blocked.

This commit updates the test suite to use the BinaryPackageUniverse
instead of the InstallabilityTester where that makes sense. The rest
of Britney has yet to be updated except where absolutely necessary (as
that will come in a later commit).

The InstallabilityTester is suffering from a lack of clear purpose
because it serves multiple. This commit extracts most of one of these
purposes into the BinaryPackageUniverse class while retaining the
original API of the InstallabilityTester.

Don't make dependencies of cruft a blocker for being a candidate. In most
cases, the cruft won't migrate to testing, so it shouldn't be a blocker. If
the cruft would be considered for migration to testing, the installability
check will catch missing deps.

At the moment, britney will always read the nuncache from disk
(possibly regenerating it before reading it). However, we can save
the "read from disk" by moving the initialization of nuninst into the
constructor of Britney and relying on clone_nuninst.
