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.

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.

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.

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

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.

Currently autopkgtest tries to install our trigger from unstable and the rest
from testing. If that fails, than autopkgtest has a fall-back to allow all
packages from unstable to be installed. This has two severe issues:
1) the version of the test and the package it came from may be out-of-sync
2) too much from unstable may be installed, even stuff that should not/is not
allowed to migrate as it breaks stuff.
Make sure that test depends also get added to triggers if they are broken.
E.g. imagine the following scenario: trigger X changes (breaks) the output
generated by Y. Package Z has Y in the test dependencies and compares the
output in the autopkgtest. We want to have the opportunity that a new version
is automatically fixing the situation.
Two use cases are currently unsupported: needs-build (autopkgtest restriction)
and test dependencies generated by autodep8.
