When we try to compute_groups for a group which has a source or a binary with
a lower version than testing, throw an exception. In the cases where this can
happen, the exception is caught. In other cases, it is not and it serves as an
assert.
This can only happen when there are multiple candidates (from multiple suites)
changing the same source or binary.
This should fix the ordering issues tested in these tests:
- tpu-unstable-binnmu
- binnmu-tpu
- tpu-with-unstable-binnmu
With this change, it should be possible to accept binNMUs from *pu again.

The issue with an implicit rollback is that the caller has no idea
whether it should invoke rollback or not if an exception occurs.

This isolates the undo handling in the new transaction object and in
doop_source, which currently generates the undo items. This commit
will be a stepping stone to rewriting the undo handling.

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

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).

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.

Previously, we split affected into a "reverse relations with a
dependency on the migrated/change package" set and a set of "the
rest". With this commit we change the sets into a set of packages
with a direct relation on the migrated/changed package and the full
set of all affected.
The change has no effect on Britney's results as the first set is only
used as an optimization to reject some items faster.

At the moment, the two are identical, but they are not intended to
remain identical (i.e. the name should eventually become the full
suite name).
